AirPerpendicularWaterIncidentRayIn the above diagram a light ray is about to leave water and enter the air. After the light entersthe air what do we expect to happen?The light ray will be bent away from the perpendicular and will speed up.The light ray will be bent towards the perpendicular and will slow down.The light ray will be bent away from the perpendicular and will slow down.○ The light ray will be bent towards the perpendicular and will speed up.

As a light ray enters a rarer medium from a denser medium, it bends away from the perpendicular.…

The side-view mirrors of most cars are convex spherical mirrors (so that the driver can see a wider angle behind the car). Suppose that the side view mirror of your car has a radius of curvature of 18 m, and that another car is 10 m in front of the mirror (behind the car). Ignore any aberration. a) Using the mirror equation to calculate how far the other car appears to be from the mirror. b) Sketch a light ray diagram including the object, the mirror, the image, and the principal light rays. c) Is the image distance smaller or larger than the object distance? Is the image smaller or larger than the object? Answer with calculations.

3 of 10 Current Attemptini tugis A tall tree is growing across a river from you. You would like to know the distance between yourself and the tree, as well as its height, but are unable to make the measurements directly. However, by using a mirror to form an image of the tree and then measuring the image distance and the image height, you can calculate the distance to the tree as well as its height. Suppose that this mirror produces an image of the sun, and the image is located 0.9399 m from the mirror. The same mirror is then used to produce an image of the tree. The image of the tree is 1.0588 m from the mirror. (a) How far away is the tree? (b) The image height of the tree has a magnitude of 0.19 m. How tall is the tree? (a) do = (b) ho=
