1. The image of a distant tree is virtual and very small when viewed in a curved mirror. The image appears to be 14.1 cm behind the mirror. What is its radius of curvature? (Use positive for concave and negative for convex).

2. An object is placed 14.5 cm in front of a convex mirror that has a focal length of -24.5 cm. Determine the location of the image.

What is the magnification?

3. How far from a concave mirror (radius 23.4 cm) must an object be placed if its image is to be at infinity?

4. The magnification of a convex mirror is +0.600x for objects 2.00 m from the mirror. What is the focal length of this mirror?

5. A beam of light in air strikes a piece of glas (n = 1.50) and is partially reflected and partially refracted. Find the angle of incidence if the angle of reflection is twice the angle of refraction.

6. A scuba diver training in a pool looks at his instructor as shown in the figure below. What angle does the ray from the instructor's face make with the perpendicular to the water at the point where the ray enters? The angle between the ray in the water and the perpendicular to the water is 25.0.
