It is desired to cast the image of a lamp, magnified 5 times, upon a wall 12 m distant from the lamp. What kind of special mirror is required, and what is is its position? 5. Compute the position and diameter of the image of the Moon in a polished sphere of diameter 20 cm. The diameter of the Moon is 3500 kg, and its distance from Earth is 384 000 km, approximately. 6. A ray of light makes an angle of 25 degrees with the normal to a plane mirror. If the mirror is turned through 6 degrees, making the angle of incidence 31 degrees, through what angle is the reflected ray rotated
