Brewster's angle Figure 23.22 Conditions at Brewster's angle.

A life-guard wants your help choosing a pair of new sun-glasses to minimize reflections from the water.  She noticed an advertisement that let one choose the angle of polarization orientation of the sunglasses. What polarization angle, if any would you advise her to choose for her new glasses.   Question 6 options:   A pair of polarizing sunglasses offers no advantage for a people near the water.   Sunglasses with a horizontally oriented polarizer would be best for reducing ocean glare.   Sunglasses with a vertically oriented polarizer would be best for reducing ocean glare.

A light ray is incident at 45° on a glass block immersed inside a liquid of refractive index nL = 1.33 as shown in the figure below. In this configuration, the refractive ray skims the bottom surface. Determine the refractive index of the glass, ng. ng 45° ng = 1.63 ng = 1.7 ng = 1.48 ng = 1.51 O ng = 1.57

A ray of light in air is incident at an angle of 25.0° on a glass slide with index of refraction 1.46. (a) At what angle is the ray refracted? from the normal (b) If the wavelength of the light in vacuum is 535 nm, find its wavelength in the glass. nm

The index of refraction of a glass plate is 1.41. What is the Brewster's angle when the plate is in the following substances? (a) air _____ °(b) water ______ °

Need help with the attached question, please help with all parts of the question.

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
