The purpose of this lab is to study the two-point interference wave pattern using light and to determine the wavelength of the light and how the fringe pattern is affected by the:
- Frequency of light
- Separation of light sources
- Amplitude of intensity of light
In this assignment, you will use a virtual simulation to investigate wave interference.
Instructions
Open the following simulation and follow the step-by-step procedure to answer the following testable question.
PhET Lab: Wave Interference SimulationTestable Question
How is the separation between nodal lines (or dark fringes) affected by the frequency of the light, separation of the light sources and the intensity of the light?
Hypothesis
Propose a hypothesis based on the testable question above.
Materials
Although you are using a simulation, you still need to prepare a list of materials. Similar to 'hands-on' activities, list all the necessary materials needed for someone to recreate the experiment.
Do not list the simulation as a material item in your lab report.
