9. Dinesh study about the mirrors. He wanted to locate one mirror in the room like Figure A2.5 with an overhead view of a room of square floor area and side L. At the center of the room is a mirror set in a vertical plane and rotating on a vertical shaft at angular speed w about an axis coming out of the page. A bright red laser beam enters from the center point on one wall of the room and strikes the mirror. As the mirror rotates, the reflected laser beam creates a red spot sweeping across the walls of the room. (a) When the spot of light on the wall is at distance x from point O, what is its speed? (b) What value of x corresponds to the minimum value for the speed? (c) What is the minimum value for the speed? (d) What is the maximum speed of the spot on the wall? (e) In what time interval does the spot change from its minimum to its maximum speed? L W L Figure A2.5 X

A physicist orients two flat mirrors at an angle of 0, = 58.3° to each other, as shown below. He then directs a horizontal ray of light toward Mirror 1. The ray reflects twice: first off Mirror 1, then Mirror 2. What angle 0, will the outgoing ray make with the surface of Mirror 2? (Enter your answer in in degrees.) Mirror 1 Mirror 2
58. A magnifying glass is a converging lens, which could be used to make a real image of an object. A small lightbulb is placed 25.0 cm in front of a convex lens with a focal length of 10.0 cm. a. G Draw a ray-tracing diagram to find the position of the image formed by the lens. b. N Calculate the location and magnification of the image to confirm the accuracy of your drawing.
A plane mirror and a concave mirror (f = 7.70 cm) are facing each other and are separated by a distance of 21.0 cm. An object is placed between the mirrors and is 10.5 cm from each mirror. Consider the light from the object that reflects first from the plane mirror and then from the concave mirror. Find the location of the image that this light produces in the concave mirror. Specify this distance relative to the concave mirror. Number H с Units Object > F
