Physics class10 light -reflection

A concave mirror gives real, inverted and same size image if the object is placed

• at F

• Between C and F

• at C

Image formed by plane mirror is

• Virtual and inverted

• Real and inverted

• Virtual and erect

10. The radius of curvature of a mirror is 20cm the focal length is

• 5 cm

• 10 cm

• 20 cm

Magnification produced by a rear view mirror fitted in vehicles

• is more than one

• is equal to one

• is less than one

The mirror used in torches, search lights and headlights of vehicle is

• concave

• convex

• plane

If an incident ray passes through the focus, the reflected ray will

• pass through the pole

• be parallel to the principal axis

• retrace its path

Focal length of a concave mirror is

• negative

• positive

• depends on the position of object

If the image is formed in front of the mirror, then the image distance will be

• positive

• negative

• positive or negative depending on the size of the object
