A) Calculate the angle for the third-order maximum of 610 nm wavelength yellow light falling on double slits separated by 0.100 mm. (in degrees)
B) What is the separation between two slits for which 600 nm light has its first maximum at an angle of 32.0 °? (in meters)
The speed of light in a transparent medium (such as glass) is less than the speed of light in a vacuum. Is this a violation of the theory of relativity.
