The next two questions pertain to the situation described below. A Michelson interferometer is set up with the interferometer arms initially with identical length (10 cm from beamsplitter to mirror), so that all the incident 1-mW power (at laser wavelength 600 nm) is detected at the detector shown. laser 600 nm 21) Then the right arm is extended slightly until no light is observed at this detector. These measurements are made with the interferometer in vacuum (n = 1). If we now place the interferometer in air (with index of refraction 1.0003), what will be the new power on the detector? a. 2.22 x 10-7 mW b. 1 mW c. 0 mW d. 4.71 x 10-4 mW e. 0.5 mW detector 22) Finally, we return the arms to being the same length. Now with the interferometer in air, what will be the new power on the detector? a. 1 mW b. 0 mW c. 2.22 × 10-7 mW
