In the image, all the rays appear to meet at F, What is F

• focal length

• focal point

• center of curvature

• reflection

Convex Mirrors produce...

• only virtual images
• virtual or real images
• only real images
• inverted images

If 'R' is radius of curvature and 'f' is focal length of a spherical mirror then the correct relation between the two is

• R = f

• R = f/2

• f = 2R

• f = R/2

Through which point on principal axis shall reflected ray pass in the following diagram of incident ray ?

• point F

• point C

• point P

• none of the above

• Plane mirror

• concave mirror

• convex mirror

• not possible
