Reflection and plane mirror

A ------------ is a Flat , Smoot Surface From Which Light is Reflection by Specular Reflection

• Plane Mirror

• Concave Mirror

• Convex Mirror

________ Which is type of image formed by diverging light rays

• object

• image

• Virtual image

The image position is equal to the object position

Reflection A light ray strikes a flat, smooth, reflecting surface at an angle of 80° to the normal. What is the angle that the reflected ray makes with the surface of the mirror?

• = 10°

• = 12°

• = 13°

• = 15°

Explain why the reflection of light off ground glass changes from diffuse to specular if you spill water on it.

• A.Water fills in the rough areas and makes the surface smoother.

• B. The law of reflection applies to individual rays of light. Rough surfaces make the light rays reflect in many different directions.

• C. Specular: window glass, smooth water, polished metal. Diffuse: paper, rough metal, ground glass, plastic milk jug

• D .The incoming light reflects off the surface of the object in all directions. This enables you to view the object from any location.

A ray of light is incident on a plane mirror at an angle of incidence 30°. The angle of reflection will be

• 30⁰

• 60⁰

• 90⁰

• 120⁰

This is an example of

• Reflection

• Refraction

• Absorption

• None of the above

When light bounces of a mirror,it is

• Reflected

• Corrected

• Absorbed

• Refracted
