1.Consider a 465 nm wavelength blue light falling on a pair of slits separated by 0.055 mm.

A) At what angle (in degrees) is the first-order maximum for the blue light? \

2.Suppose you have a lens system that is to be used primarily for 690 nm red light.

B)What is the second thinnest coating of magnesium fluorite, which has an index of refraction of n = 1.38, that would be non-reflective for this wavelength? Assume the index of refraction of the lens is bigger than 1.38, and enter your answer in nanometers.

3.Light with a wavelength of λ = 682 nm. is incident on a single slit of width w = 1.25 micrometers. A screen is located L = 0.25 m behind the slit and an interference pattern has formed on it.

C)What is the distance between the central bright spot and the first dark fringe, D, in meters?

4.Consider a single slit that produces its first minimum for 634 nm light at an angle of 28.5°.λ = 634 nm
θ₁ = 28.5 °

D)How wide is the single slit in meters?

E)At what angle (in degrees) will the second minimum be?

5. The figure shows a double slit located a distance x = 1.85 m from a screen, with the distance from the center of the screen to a bright fringe given by y. When the distance d between the slits is large compared to the wavelength λ, there will be numerous such bright fringes.

F)

Find the wavelength of light, in nanometers, that produces fringes 10.5 mm apart on a screen 1.85 m from double slits separated by 0.115 mm. You may assume that the angle θ is small.

Blue light of wavelength 470 nm is used to illuminate a pair of narrow slits that are 0.020 mm apart and 1.60 m from a screen. (a) What is the angular position of the second-order minimum (dark spot)? (b) What is the distance on the screen between the central maximum and the second-order minimum? (c) The reason there is a dark spot at this location on the screen is because light from one slit has to travel further than light...
