Problem 1: You want to test a special watertight monochromatic light source in an un- derwater environment. If the light source shines its beam of electromagnetic radiation into your eyes when you and the light source are above the water, with both your eyes and the light source immersed in air, the beam appears to your eyes to have a deep violet color. The index of refraction of water is about 1.33 What color, if any, would your eyes perceive the beam to have when you and the light source are submerged in water – and why? (A) No color. The beam would become invisible under water because its wavelength in water is shorter than in air, corresponding to a wavelength of ultra-violet light. The beam's wavelength in the water determines its visibility to the eye under water, and ultra-violet light is not visible to the human eye. (B) Same color as in air, above the water, i.e., deep violet. Under water, the beam would have the same wavelength as in air. The beam's wavelength in the water…
w9-10 A diamond in air is illuminated with white light. On one particular facet, the angle of incidence is 25.70°. Inside the diamond, red light (λ = 660.0 nm in vacuum) is refracted at 10.88° with respect to the normal; blue light (λ = 470.0 nm in vacuum) is refracted at 10.13°. How would a diamond look if there were no dispersion? a. The diamond would look white. b. The diamond would look red. c. The diamond would look blue. d. The diamond would be clear.
A diffraction grating with n = 2.5E-05 lines/nm is used to separate two colors of light. The angle between their first maxima is Δθ ≡ θ1 - θ2 = 0.12 degrees, and the first light has wavelength λ1 = 530 nm. Part (a) Find θ1 using n and λ1 in radians. Part (b) Find θ2 Part (c) Find the value of the wavelength of the second color λ2 in nm.

a) Estimate the limiting angle of resolution for this eye, assuming its resolution is limited only by diffraction. b) Determine the minimum separation distance d between two point sources that the eye can distinguish if the point sources are a distance L = 25 cm from the observe c) Find what diameter the pupil of a human eye must have for its limiting angle of resolution to be 0.6 minutes of arc (equal to 1.75 ✕ 10−4 rad) when the light has a wavelength of 515 nm. Assume that diffraction is the only limitation on resolution. Express your answer in millimeters. Hint
1. A flashlight held 1.3 m above the surface of a water tank shines a beam of light on the water (index of refraction n 1.33). The light hits the water 2.7 m away from the edge of the tank, where the flashlight is held. The water tank is 2.1 m deep. (a) What is the incident angle relative to the normal? (b) What is the transmitted angle relative to the normal? (c) Where does the light ray hit the bottom of the water tank, mea- sured from the edge of the tank where the flashlight is held? light ray 2.7 m d=? = water tank 1.3 m 2.1 m
