Michelson Interferometer Kit with He-Ne-Laser

AGN-228B

Principle and Working :
When a coherent light beam enters into beam splitter, it is divided into two parts, thus two beams
travel in different directions, are relected into each other through two mirrors forming
interference patterns when they are combined and superimposed. In the present setup,
measuring the wavelength of sodium light or He-Ne laser, using an equation: λ=2.D/n
where, D is the total displacement whereas n is the number of intensity maxima counted.
