General Aim of Michelson Interferometer Experiment
To determine the refractive index of a thin transparent plate.
Michelson Interferometer Experiment Method
Michelson’s interferometer procedure.
Learning Objectives of Michelson Interferometer Experiment
By the end of the experiment, the student should be able to: Construct the Michelson’s interferometer.
Recognize the function of each component in the interferometer.
Understand the operation of the interferometer.
Interpret the observed in the interference pattern.
Theory of Michelson Interferometer Experiment
Monochromatic light beam from a laser source is splitted into two beams. the two beams are reflected back from two mirrors to a screen, where interference pattern is observed. By moving one of the two mirrors or both, the phase difference between the two beams changes and the fringes crossing the field of vision changes in number accordingly.
Michelson Interferometer Principle
In michelson interferometer experiment, The number of fringes crossing the field of vision is counted as one (or both) of the two mirrors is moved or by rotating the glass plate stage through angle . hence the wavelength of laser and the refractive index of the glass plate could be determined.
“With the onset of the COVID-19 pandemic, we found ourselves in a situation that forced us to act quickly to find the best solution available to provide our students with a quality molecular genetics laboratory experience.”
'' Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab, solution: PraxiLabs.''
" PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs."
"Great user experience and impressive interaction, I am very pleased to have tried the simulations and will continue to do so."
