A light with a wavelength of 500nm is incident on a double slit opening with a width of 40 microm. If the screen is 0.9m away from the open
A) what is the maximum number of maximums we will see on the screen?
B) If I increase the wavelength, will I see more or less or the same number of maximums?
C) How far is would the 4th minimum be from the center of the central maximum?
