For an incident ray directed towards the center of curvature of a spherical mirror, the reflected ray
retraces its path
passes through the focus
passes through the pole
become parallel to the principal axis
In simple periscope, the two plane mirror inclined an angle of
90 °
45 °
180 °
360 °
For a spherical mirror:
f = R
f = 2R
When two mirrors are kept parallel to each other, Then the number of images formed is:
Zero
One
Infinite
Two
A man standing in front of a plane mirror, finds his image at a distance 6 m from himself. Then the distance of man from the mirror is:
3 m
6 m
12 m
2 m
A real and enlarged image can be obtained by using a:
convex mirror
plane mirror
concave mirror
either convex or plane mirror
At what distance from a concave mirror of focal length 25 cm should an object be placed so that the size of image is equal to the size of the object?
50 cm
75 cm
12.5 cm
20 cm
By law of reflection
The point at which the incident ray strikes the reflecting surface is:
Angle of incidence
Angle of reflection
Point of incidence
Normal
Regular reflection occurs when a beam of light falls on a
book
