Problem 3 [25 pts]: White light, with a uniform intensity across the visible wavelength range of 400 nm to 720 nm, is perpendicularly incident on a glass film, of index of refraction ng = 1.52 and thickness d = 340 nm,, suspended in air. At what wavelength 2 is the light reflected by the film brightest to an observer?

Q1 Thin Film Engine oil (n = 1.50) has spilled onto a smooth flat lake (n = 1.33), spreading into a thin surface film of thickness, d. Sunlight illuminates the lake, reflecting from an incident angle of 45° to your eye. Your eye detects sunlight in the 400 to 740 nm wavelength range. (a) [3 mark] State an equation for wavelength, 2m, that satisfies the bright intensity fringe condition at the 45° viewing angle. (b) [2 marks] Determine the minimum...

Light of wavelength 420 nm is incident normally on a film of
water 1.0 µm thick. The index of refraction of water is 1.33.
(a) What is the wavelength of the light in the water?
(b) How many wavelengths are contained in the distance 2t,
where t is the thickness of the film? (Do not round your
answer to a whole number.)
(c) What is the phase difference between the wave reflected from
the top of the air-water interface and...

10.A narrow beam of white light is incident normally on the surface of a triangular silicate flint glass prism with one angle of 90. The index of refraction for violet light is 1.66 and for red light is 1.61. The angle in the prism is equal to 30° of glass. a. On the diagram below show an approximate sketch for the refracted light from the opposite face of the prism. Air B White light 780° Glass Calculate angular separation between...

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
