Question

1. A single-slit interference pattern using blue light with a wavelength of 438 nm creates a central maximum that is 6.50 cm wide. If the slit width used is 17.5 mm, how far away is the screen?

2. A picture frame manufacturer wishes to design picture frames that provide minimal glare from the glass cover. In order to achieve this, a thin plastic film(n=1.35) is placed on the glass surface(n=1.52). If light reflected in the middle of the visible spectrum with a wavelength of 550nm is to be minimized, what film thickness is required?
