Which of the following is a concave mirror?

• 
• 
• 
• 

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 point on the spherical mirror at the middle of the surface is called

• focus

• centre of curvature

• pole

• radius of curvature

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

• 24

• 12

• 6

• 1.2

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

• Enlarged size

• virtual image

• Real image

• inverted image

The angle of incidence of a ray of light passing through the centre of curvature of a concave mirror is ........... degree

• 105

• 180

• 90

• 0

According to laws of reflection,

• angle of incidence > angle of reflection

• angle of incidence < angle of reflection

• angle of incidence = angle of reflection

• both 1 and 2
