Reflection by a Plane Mirror

The transparent part of a mirror that supports the reflective coating is usually made of:

• Plastic

• Metal

• Glass

• Wood

What is the reflective coating on a mirror usually made from?

• Silver

• Gold

• Copper

• Iron

A plane mirror that we use everyday:

• reflects all the light

• reflects and absorbs the light

• scatters all the light

• refracts all the light

According to the laws of reflection, the incident ray, the reflected ray, and the normal all lie:

• In different planes

• In the same plane

• Perpendicular to each other

• At various angles to each other

What kind of reflection occurs when light hits a rough surface?

• Regular reflection

• Total internal reflection

• Diffused reflection

• Refraction

When light reflects off a smooth, shiny surface, the angle of reflection is:

• Equal to the angle of incidence

• Greater than the angle of incidence

• Less than the angle of incidence

• Randomly distributed

Why do we see a clear image in a mirror but not on a piece of paper?

• Because the paper absorbs light

• Because the mirror produces a regular reflection

• Because the paper scatters light in many directions

• Because the mirror transmits light

Which type of surface would cause parallel light beams to scatter in many directions?

• Polished metal

• Mirror

• Smooth glass

• Wood

For reflection in mirrors, the incident ray, the reflected ray and the normal all lie on the same plane. What is the plane here?

• Mirror

• Plane perpendicular to the mirror

• incident ray

• reflected ray
