1 a michelson interferometer is illuminated with a normal, Ask an Expert

Academics

1) A Michelson interferometer is illuminated with a normal, monochromatic beam of light. When one of the mirrors of the interferometer is moved 2.53 X 10^-5 m it is observed that 92 fringe pairs (bright and dark) pass by in the process. Determine the wavelength of the incident light used.

2) The mirrors on a Fabry!Perot interferometer have a reflection coefficient r = 0.908 For this interferometer find:

a.) The finesse

b.) The coefficient of finesse

c.) The half width at half!maximum for the transmittance peaks
