Question

1. What is a common example of a converging mirror?

2. Where must you (the object) stand in front of a converging mirror if you want to see an upright,
virtual image of yourself? What is the size of the image compared to the object?
3. A converging mirror produces no image when the object is at
4. If the centre of curvature in a converging mirror is at 10cm, the focal point will be at
om

Answer 1

1)Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays.

2)The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point.

3)When the object is located at the focal point, no image is formed. As discussed earlier in Lesson 3, light rays from the same point on the object will reflect off the mirror and neither converge nor diverge.

sorry I don't know 4one
