1) What is true for a beam of light refracting when passing in between two different (optical) materials?

The frequency of the wave is different in different materials
The length of the wave is different in different materials
The speed of the wave is different in different materials
All of the above
Only answers 2 and 3

2) A light ray strikes an air/water surface at an angle of 36 degrees with respect to the normal. The angle of refraction is (_____) when the direction of the ray is from air to water, and (_____) from water to air. (Only write the numbers; 3 significant figures)

3) What is the critical angle for total reflexion from water to air? (Number only; 3 significant figures)

6) An object is placed a certain distance away from a convex (converging) lens. Assign the correct image properties to the object's position (f stands for the lens's focal length)

___ Object distance > 2f A. Virtual, upright, and larger

___ f< object distance < 2f B. Real, inverted, and larger

___ object distance < f C. Real, inverted, and smaller

When a vertical beam of light passes through a transparent medium, the rate at which its intensity I decreases is proportional to I(t), where t represents the thickness of the medium (in feet). In clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity I0 of the incident beam. What is the intensity of the beam 13 feet below the surface? (Give your answer in terms of I0. Round any constants or coefficients to five...

Consider how the intensity of light changes as it passes between two Polaroid disks at different angles to each other. (For this scenario, suppose that the polaroid closest to the light source remains fixed with the zero degree marking pointing straight up. Therefore, the second Polaroid disk is the one being rotated, and the angles for the graph should be the angle between the zero degree marking of the first disk and the position of the second disk. ) a....

A light ray strikes the perfectly smooth boundary between two different materials. The index of refraction of the material before the boundary is lower than that of the material after the boundary. On the basis of this information, the light ray will be a. partially transmitted in a direction deviating more from the normal and partially reflected. b. partially transmitted in a direction deviating less from the normal and partially reflected. c. partially transmitted exactly in the same direction and...
