Answer:
1.00029
Explanation:
A wave is a disturbance which travels through a medium and transfers energy without displacing the medium itself.
interference is one of the characteristics of a wave motion
The Michelson interferometer produces interference fringes by splitting a beam of monochromatic light so that one beam strikes a fixed mirror and the other a movable mirror. When the reflected beams are reflected, an interference pattern results.
∝Δm=Δud
∝=wavelength 500nm
Δm=number of fringes
d=length 9f the Michelson interferometer chamber
Δu= change in refractive index
500*10^-9*29=0.05*Δu
Δu=0.00029
REFRACTIVE INDEX=1+0.00029
refractive index=
1.00029
