Reflection and Mirrors

An ________ is a copy of an object that is formed by reflected light.

Diffuse reflection occurs when light reflects off a smooth surface and forms a blurry image.

• True

• False - rough surface

• False - regular reflection

• None of the above

Which is true about the law of reflection

• The angle at which light rays reflect off a surface is equal to the angle at which the incident rays strike the surface.

• The angle at which light rays are absorbed is equal to the angle at which the incident rays strike the surface

• the angle at which light rays are reflected is always 90 degrees to the angle at which the incident rays strike the surface

Diffuse reflection

Regular reflection

Why can you see your reflection on a mirror but not on a piece of paper?

Any surface that reflects light and forms an image is considered a mirror.

• True

• False

What is the angle of the incidence ray and what is the angle of the reflecting ray?

• Incidence ray: 90 deg

• Incidence ray: 20 deg

• Incidence ray: 30 deg

• Reflecting ray: 30 deg

• Reflecting ray: 90 deg

Which of the following would be the proper labels...

• A: incident ray

• B: incident ray

• A: reflecting ray

• B: reflecting ray

Explain the following statement:

"The shape of a mirror’s surface determines the type of image it forms. "
