SC LIGHTS

What three things may happen to light that strikes an object? 

• The light may be reflected, transmitted or absorbed.

• The light may be reflected and refracted.

• The light may be absorbed and transmitted.

______ is a copy of the object formed by reflected or refracted rays of light

• reflection

• object

• refraction

• image

The two kinds of reflection are 

• 
  transparent and translucent

• regular and diffuse

• opaque and translucent

The illustration shows a light ray striking an object.
In the illustration, the light ray striking the object is-

• absorbed

• stopped

• refracted

• reflected

A student placed a pencil in a cup of water.  The pencil appears broken because

• light always travels in a straight line

• light makes the water in the glass evaporate

• light bends when it passes through water

• light reflects the pencil on the water's surface

This shows the phenomenon known as....

• reflection

• mirror

• refraction

• focal point

Angle between normal and the ray reaching the boundary is

• angle of refraction.

• angle of incident

• angle of reflection

• angle of incidence

Glasses are a use of:

• reflection

• refraction

Which of these provides the best explanation for why the pencil appears broken?

• The pencil absorbs the light rays that hit it.

• Light rays are bent by the water in the glass.

• Water reflects light rays away from the pencil.

• The surface of the water reflects the light rays.

Light travels in straight lines until reflected by another object. Which illustration best shows the light being reflected?

•
