Spherical Mirrors Quiz

What are spherical mirrors?

• Mirrors with flat reflecting surfaces

• Mirrors with reflecting surfaces as part of a sphere

• Cylindrical mirrors

• Any curved mirrors

What is the radius of curvature (R) of a mirror?

• Distance from the pole to the principal focus

• Distance between the mirror and the principal axis

• Radius of the sphere of which the mirror is a part

• Diameter of the mirror's reflecting surface

The midpoint of the reflecting surface of a mirror is called the:

• Centre of curvature

• Principal focus

• Pole

• Aperture

The straight line connecting the pole of the mirror and the center of curvature is known as the:

• Radius of curvature

• Principal axis

• Aperture

• Normal

What is the aperture of a spherical mirror?

• The radius of curvature

• The reflecting surface of the mirror

• The distance from the pole to the principal focus

• The distance between the centre of curvature and the mirror

Which of the following is true about the angles of incidence and reflection in spherical mirrors?

• They are always unequal

• The angle of incidence is always greater

• They are always equal

• It depends on the type of mirror

Where do rays of light incident on a concave mirror, parallel to the principal axis, converge after reflection?

• At the pole of the mirror

• At the principal focus of the mirror

• At the center of curvature of the mirror

• On the reflecting surface itself

What is the focal length of a spherical mirror?

• Equal to the radius of curvature

• Twice the radius of curvature

• Half of the radius of curvature

• Three times the radius of curvature

A ray of light incident on a spherical mirror through the principal focus will:

• Reflect back through the focus

• Reflect parallel to the principal axis

• Pass through the center of curvature

• Pass undeviated

A ray of light incident at the pole of a spherical mirror making a definite angle with the principal axis will:

• Pass through the center of curvature

• Reflect parallel to the principal axis

• Reflect at the same angle with the principal axis

• Reflect through the principal focus
