Light & Reflection

which of the following is not a property of the image formed by a [lane mirror?

• virtual and erect

• Object size = image size

• object distance = image distance

• Real and inverted

Four students A, B, C and D performed the experiment to determine the focal length of a concave mirror by obtaining the image of a distant tree on a screen. They measured the distances between the screen and the mirror as shown in the above figure.

The correct way of measuring accurate focal length of the mirror is

• A

• B

• C

• D

which of the following ray diagrams is correct for the ray of light incident on a concave mirror as shown in the figure 10.6?

• A

• B

• C

• D

Convex mirror is also called as

• converging mirror

• diverging mirror

• plane mirror

• silver mirror

The relation between focal length and radius of curvature is

• R = 2f

• 1/f = 2R

• f = R/2

• R = 2/f

The focal length of a plane mirror is ........

• infinite

• zero

• 1m

• 100m

A convex mirror has a focal length 12 cm. Then its radius of curvature is ........ cm

• 24

• 12

• 6

• 1.2

When the object is in between the centre of curvature (C) and focus (F) of a concave mirror, then the position of the image is ...........

• At focus

• At the centre of curvature

• at infinity

• beyond the centre of curvature

Which of the following characteristic of an image formed for a convex mirror?
