Question

For a real image to bo formed by a concave mirror, the object must be: further from the mirror than center of the mirror. anywhere on the reflective side of the mirror. further from the mirror than focal length of tlio mirror. closer to the mirror than center of the mirror. closer to the mirror than focal length of the mirror. The image produced by a convex mirror of an upright object in front of the mirror is always: virtual, erect, and larger than the object. virtual, erect, and smaller than the object. real, erect, and larger than the object. real, erect, and smaller than the object. real, inverted, and smaller than the object. virtual, inverted, and larger than the object. virtual, inverted, and smaller than the object. real, inverted, and larger than the object. cm A 2.0 cm high object is placed 20 cm in front of a concave mirror of radius of curvature 30. What is the image location? Is it. inverted or upright? Ts it vitual or real?

Explanation / Answer

2) (c) farther from the mirror than focal length of the mirror

3) (b) virtual, erect and smaller than the object

4) -1/15 = 1/v -1/20 => v = -60 i.e. image is on same side of object and at a distance 60 cm from mirror.

height = 60 x 2/20 = 6 cm.....real, inverted
