1. Two plane mirrors M₁ and M2 are separated my 118°. A ray strikes mirror M₁, at Bi (angle of incidence), and leaves the mirror Mz, at Or = 62° (angle of reflection). Find the angle of incidence 0, that strikes the mirror M₁. 2. A light ray in air is incident on a water surface at a 30° angle of incidence. Find a) The angle of reflection. b) The angle of refraction. 3. A 2.57-cm-tall object is placed 7.10 cm to the left of a diverging lens whose focal length is 5.08 cm. Please answer the following questions. Lote b) c) d) Find the image distance and determine whether the image is real or virtual. Determine the magnification of the lens. Determine the image height. Please draw a diagram and label each term. 4. A convex mirror is used to reflect light from an object placed 65 cm in front of the mirror. The focal length of the mirror is 45 cm. Find the location of the image its size relative to the object.
