Physics Lab Report Sample: Spectrometry
Spectrometry is a fundamental technique in analytical chemistry used for identifying and quantifying the elements or compounds present in a sample based on the interaction of electromagnetic radiation with matter. In this experiment, the objective was to use spectrometry to determine the wavelength of light emitted from a hydrogen gas discharge tube. The spectrometer was calibrated using known spectral lines of hydrogen, and the Balmer series lines were observed and measured. The results obtained demonstrated the practical application of spectrometry in identifying wavelengths and energy levels in atomic spectra.
Spectrometry is a valuable analytical tool used in various scientific fields, particularly in chemistry and physics, to investigate the interaction of light with matter. In the realm of atomic physics, spectrometry plays a pivotal role in analyzing the spectral lines emitted by atoms. The study of these lines provides insights into the energy levels of electrons within atoms.
One of the key applications of spectrometry is the analysis of atomic spectra. The Balmer series, specifically, is a set of spectral lines in the visible region associated with the hydrogen atom. These lines correspond to transitions of the hydrogen electron between different energy levels. By measuring the wavelengths of these lines, the energy levels of the electrons can be determined.
In this experiment, a spectrometer was used to investigate the wavelengths of the spectral lines emitted by a hydrogen gas discharge tube. By analyzing the visible spectral lines and applying the Balmer formula, the energy levels of the hydrogen atom could be determined.
The following apparatus was used in the experiment:
- Hydrogen gas discharge tube.
- Diffraction grating.
- High-voltage power supply.
- Wavelength calibration lamp.
- Vernier calipers.
- The spectrometer was calibrated using a wavelength calibration lamp with known spectral lines. This step ensured the accuracy of the spectrometer’s measurements.
- The hydrogen gas discharge tube was powered using the high-voltage supply, causing it to emit light. The emitted light passed through the spectrometer.
- The spectrometer was adjusted until the spectral lines were visible and well-focused.
- The positions of the Balmer series lines in the spectrum were noted. The Vernier calipers and ruler were used to measure the distances on the scale.
The following spectral lines of the hydrogen spectrum were observed:
- Red line (n=3 to n=2)
- Blue-green line (n=4 to n=2)
- Violet line (n=5 to n=2)
The measured values for the angles and positions of the spectral lines are as follows:
- Red line: θ = 27.5°
- Blue-green line: θ = 43.8°
- Violet line: θ = 53.2°
The known wavelengths of the Balmer lines (in vacuum) are:
- Red line: λ = 656.3 nm
- Blue-green line: λ = 486.1 nm
- Violet line: λ = 434.0 nm
Using the spectrometer equation (d sin θ = mλ, where d is the grating spacing, θ is the angle, m is the order, and λ is the wavelength), the wavelengths of the observed lines were calculated. The calculated values were compared with the known wavelengths.
The experimental results demonstrate the successful use of spectrometry to measure the wavelengths of the Balmer series lines in the hydrogen spectrum. The measured values for the red, blue-green, and violet lines were in good agreement with the known wavelengths, indicating the accuracy of the spectrometer.
The Balmer formula, which relates the observed wavelengths to the energy levels of the electron in the hydrogen atom, was applied successfully in this experiment. The formula is given by:
1/λ = R_H * (1/n₁² – 1/n₂²)
In this form, we can see that the equation relates the reciprocal of the observed wavelength (1/λ) to the Rydberg constant for hydrogen (R_H) multiplied by the difference between the reciprocals of the squares of two integer values (1/n₁² and 1/n₂²), which correspond to different energy levels of the electron within the hydrogen atom. This formula helps us understand how the wavelengths of spectral lines in hydrogen are determined by the energy levels of the electrons, with the difference in energy levels affecting the observed wavelengths.
- λ is the observed wavelength.
- RH is the Rydberg constant.
- n1 and n2 are the principal quantum numbers for the initial and final energy levels.
The experiment’s success in measuring the wavelengths of the hydrogen spectrum’s spectral lines reinforces the practical significance of spectrometry in atomic physics. It allows scientists and researchers to gain insights into the energy levels and electronic transitions within atoms, contributing to a deeper understanding of atomic structure and behavior.
Spectrometry is a powerful analytical tool used to investigate the interaction of electromagnetic radiation with matter. In this experiment, the spectrometer was employed to measure the wavelengths of spectral lines emitted by a hydrogen gas discharge tube. The results demonstrated the accuracy and reliability of the spectrometer, as the measured values aligned closely with the known wavelengths. This experiment highlights the practical application of spectrometry in atomic physics and its role in unraveling the mysteries of atomic spectra.

Measuring the Speed of Light: A Physics Lab Report Sample
This physics lab report presents the experimental measurement of the speed of light using a simple but accurate method based on time-of-flight measurements. The measured value closely aligns with the accepted speed of light, validating the experimental approach.
The speed of light, denoted by ‘c,’ is a fundamental constant in physics and plays a pivotal role in various scientific fields. Measuring the speed of light experimentally is not only an exciting endeavor but also an excellent opportunity to comprehend the precision of scientific techniques. This lab aims to determine the speed of light through a straightforward yet accurate method.
Materials and Methods:
- A straight, long hallway (preferably indoors)
- A rotating mirror mounted on a stand
- A laser beam generator
- A detector with a timing mechanism
- Meter sticks
- The rotating mirror and detector are set at the two ends of the hallway, facing each other. The mirror rotates at a known constant rate.
- A laser beam is emitted from the generator, and it travels along the hallway, hits the rotating mirror, and is reflected back to the detector.
- As the mirror rotates, it gradually points the reflected laser beam towards the detector. When the detector receives the reflected beam, it records the time.
- To calculate the speed of light, we need to measure the angle through which the mirror rotates during the time it takes for the laser beam to travel from the generator to the mirror and back to the detector.
- Using protractors and meter sticks, we measure the distance from the generator to the mirror and from the mirror to the detector.
- Using the time measured by the detector and the angular displacement of the mirror, we can calculate the speed of light using the equation:c = 2d / (t * sin^(θ/2))where:
- is the speed of light,
- is the distance from the mirror to the detector,
- is the time recorded by the detector, and
- is the angular displacement of the mirror.
Using the measurements obtained during the experiment, we calculate the speed of light, as follows:
- Distance from the mirror to the detector () = 15 meters
- Time measured by the detector () = 75 nanoseconds
- Angular displacement of the mirror () = 30 degrees
c = 2d / (t * sin(θ/2)) = 3.00*10^8 m/s
This represents the calculation for the speed of light, which is approximately 3.00 x 10^8 meters per second.
The calculated value for the speed of light is approximately 3.00 x 10^8 m/s, which is very close to the accepted value of approximately 2.998 x 10^8 m/s. The slight discrepancy may be attributed to factors such as experimental error, equipment precision, and environmental conditions.
This physics lab experiment successfully measured the speed of light using a straightforward method. The result obtained closely matches the accepted value, demonstrating the effectiveness of the approach and the remarkable precision of modern scientific techniques.
