A ray of light is incident on a plane mirror making an angle of 90° with the mirror surface. The angle of
reflection for this ray of light will be :
45o
90o
0o
60o
A diverging mirror is :
a plane mirror
a convex mirror
a concave mirror
a shaving mirror
If R is the radius of curvature of a spherical mirror and f is its focal length, then :
R = f
R = 2f
R = f / 2
R = 3f
The angle of incidence for a ray of light passing through the centre of curvature of a concave mirror is :
45°
90°
0°
180°
In the concave reflector of a torch, the bulb is placed :
between the pole and focus of reflector
at the focus of reflector
between focus and centre of curvature of reflector
at the centre of curvature of reflector
The real image formed by a concave mirror is smaller than the object if the object is :
between centre of curvature and focus
at a distance greater than radius of curvature
at a distance equal to radius of curvature
at a distance equal to focal length
According to New Cartesian Sign Convention :
focal length of concave mirror is positive and that of convex mirror is negative
focal length of both concave and convex mirrors is positive
focal length of both concave and convex mirrors is negative
focal length of concave mirror is negative and that of convex mirror is positive
