Study Notes
Zeeman Effect Experiment
- Objective: To study the normal Zeeman effect, the principle of Fabry-Perot interferometers, and determine the Bohr magneton.
Theory
- Normal Zeeman Effect: A single spectral line splits into multiple lines when the light source is in a magnetic field. This phenomenon was discovered by Peter Zeeman.
- Zeeman Effect Types: There are normal and anomalous Zeeman effects. This experiment focuses on the normal Zeeman effect.
- Cadmium Spectral Line: The experiment uses a cadmium spectral line with a wavelength of 643.8 nm. The cadmium atoms are in a singlet system with a spin value of S=0.
- Orbital Angular Momentum (L): When atoms are in a magnetic field, the energy levels separate, as the orbital angular momentum has specific size and direction.
- Space Quantization: Quantum mechanics provides evidence that angular momentum is space-quantized.
- Bohr Magneton: A fundamental constant related to the magnetic moment of an electron.
Experimental Setup
- Fabry-Perot Interferometer: Used to measure the wavelength shifts due to the Zeeman effect in high precision..
- Cadmium Lamp: Emits light used for the experiment.
- Electromagnet: Creates the magnetic field.
- Other Equipment: Power supplies, variable transformers, components for optical setup for the experiment.
Procedure
- Setup: Arrange the components according to a diagram (e.g., Figure 7).
- Measurement: Measure the radii of the rings in the interference pattern for varying current intensities in the electromagnet, then calculate Bohr magneton.
- Data Collection: Collect data(e.g. current, magnetic field, ring radii) to analyze the changes in wavelength with applied magnetic field
- Graphing: Plot the data to visually interpret the relationship between the magnetic field strength and the splitting of the spectral lines.
Analyzing Results
- Bohr Magneton Calculation: Derive Bohr magneton values based on the collected data.
- Data Analysis: Analyze the collected data to calculate Bohr magneton values for different current values. This is done graphically by plotting the wave number difference against the magnetic field to find the slope.
- Comparison: Compare the experimentally determined values with theoretical values.
Additional Considerations
- Longitudinal and Transverse Zeeman Effects: Recognize the difference between longitudinal and transverse Zeeman effects.
- Spectral Lines: Note the splitting of spectral lines into several components in the presence of a magnetic field.
- Selection Rules: Understand the rules governing allowed transitions between energy levels, which affects the observed spectrum.
- Equipment Calibration: Understand that different instruments have different units and error ranges.
