Light reflection

The mirror always form virtual and diminished image

• Plane mirror

• convex mirror

• concave mirror

• any of these

The magnification of a plane mirror is:

• +1

• -1

• Greater than 1

• Less than 1

In a mirror the left side the object appears as right and vice versa. This property is called -----

• Reflection

• Refraction

• Lateral inversion

• None

-0.23 is the magnification produced by a mirror. Name the type of mirror

• Concave

• Convex

• Plane

• We cannot predict by the value

The focal length of a convex mirror is 30 cm. Its radius of curvature is:

• 15 cm

• 45 cm

• -50 cm

• 60 cm

If the radius of curvature of a mirror is 40 cm. Then its focal length is:

• 20 cm

• 80 cm

• 30 cm

• 10 cm

The angle between the incident ray and reflected ray is 64 degree.Then angle of reflection is:

• 64

• 26

• 36

• 46

 $$  The angle between the reflecting surface and the incident ray is 70 degree. Then the angle of incidence is:

• 35

• 45

• 30

• 50

If a light ray falls normally to a reflecting surface, then its angle of reflection is ----- degree

• 90

• 45

• 180

• 0

The mirror used in solar furnace is:

• Plane

• Convex

• Concave

• Any of these
