Doctors use concave mirrors for examining the eyes, ears, nose and throat.

Correct! Wrong!

Concave mirror forms clear and magnified image when the object is within focus. Hence, doctors use concave mirrors for examining the eyes, ears, nose and throat.

A person is waving his left hand looking into a plane mirror will observe that the image is ____.

Correct! Wrong!

A person waving his left hand looking into a plane mirror, will observe that the image is waving its right hand.

The image of an object formed using the convex side of a steel spoon is ____ in size.

Correct! Wrong!

The image of an object formed using the convex side of a steel spoon is erect and smaller in size.

An image that cannot be formed on a screen is called a virtual image.

Correct! Wrong!

An image that cannot be formed on a screen is called a virtual image.

The outer surface of a stainless steel spoon acts as a ____ mirror.

Correct! Wrong!

The outer surface of a stainless steel spoon acts as a convex mirror.

Distances measured above the principal axis are taken as positive.

Correct! Wrong!

According to the new cartesian sign convention, distances measured above the principal axis are taken as positive.

Convex mirrors can form images of objects spread over a large area. So, these help drivers to see the traffic behind them.

Correct! Wrong!

Convex mirrors can form images of objects spread over a large area. So, these help drivers to see the traffic behind them.

For a concave mirror the focal length is ____ and the radius of curvature is ____.

Correct! Wrong!

For a concave mirror the both focal length and radius of the curvature are taken negative.

Angle of incidence is ____ equal to angle of reflection.

Correct! Wrong!

Angle of incidence is always equal to angle of reflection.

A mirror changes the direction of light that falls on it. This property is called ____ of light.

Correct! Wrong!

A mirror changes the direction of light that falls on it. This property is called reflection of light.

If you stand in front of a plane mirror, and scratch your left cheek, you find your image scratching its right cheek.

Correct! Wrong!

In a plane mirror, the image formed is always laterally inverted, which means that the right side of an object appears on the left in the image, and vice versa. Hence, if you stand in front of a plane mirror, and scratch your left cheek, you find your image scratching its right cheek.
