A
The angle of incidence for a ray of light having zero reflection angle is
Zero
Converging mirror
Concave mirror
What is the relationship between focal length and radius of curvature
f=R/2 or R=2f
When the object is placed at centre of curvature of a concave mirror where the image is formed
At C
The name of the imaginary line passing through principal focus,centre of curvature and pole of the mirror
Principal axis
Which is the only mirror which can form real images
Concave mirror
The image formed by a concave mirror is real inverted and of the same size as that of the object. The position of object should be
At the centre of curvature
Centre of the mirror
Pole
Light from the sun falling on a concave mirror will converge at a point called
Principal focus
What is the angle of incidence for normal incidence
zero
Radius of curvature of a spherical mirror is 40 cm. What is its focal length
20 cm
An incident ray makes an angle of 35° with the surface of a plane mirror what is the angle of reflection
55°
