A real and enlarged image can be obtained by using a:
convex mirror
plane mirror
concave mirror
either convex or plane mirror
An object is placed between two plane mirrors inclined at an angle of 50 °. Then the number of images formed is
5
7
8
10
Regular reflection occurs when a beam of light falls on a
book
room
table
The radius of curvature of a convex mirror is 40 cm. Then the focal length is
80 cm
10 cm
50 cm
20 cm
For what position of object, the image formed by a concave mirror is magnified and erect?
Object is at centre of curvature
Object is at focus
Object is in between principle focus and the pole
Object is at pole
The return of light into the same medium after striking a surface is called
Refraction
Reflection
Transmission
Radiation
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
Convex mirror is used as
a shaving mirror
a rear view mirror
a reflector
a doctor's head mirror
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
The image formed by a plane mirror is:
erect and diminished
erect and enlarged
inverted and of same size
erect and of same size
