Please help my homework! how to solve this problem. 1.17(ch1) In one of early versions of Michelson's interferometer, thearms were about 50cm long. What would be the expected shift Nwhen he rotated the apparatus through 90°, assuming that=590nm and that the expected speed of the earth relative tothe ether was 3x104m/s? answer is n=0.017 Please help my homework! how to solve this problem. 1.17(ch1) In one of early versions of Michelson's interferometer, thearms were about 50cm long.

Explanation / Answer

Given : Length ( L ) = 50 cm = 50 * 10-2 m Wavelength ( ) = 590 nm = 590 * 10-9m    n = 2L /           = 2 (50* 10-2 m) / (590 * 10-9 m)           =0.0169          ˜0.017 I hope it helps you
