Question

Laser light with a wavelength of 480.0 nm is sent to a beanm splitter at A in the diagram below. The beamsplitter reflects half of the light to the mirror at B and transmits half of the light to the mirror at C. After reflecting from their respective mirrors the two beams strike the beamsplitter again and re- combine. Some of the light then reflects to a detector at D A. 8. [2pt] The distance from A to C is 3000.0 nm longer than the distance from A to B, and each wave reflects twice from a material with a higher index of refraction than air. According to our rules for determining phase diffe difference for the two beams? rence, what is the phase 9. [lpt] In this case, do the two light beams interfere 1.) con- structively, 2.) destructively, or 3.) somewhere in between?

For problem number 8, the solution should have three significant figures
