• True

• Flase

Identify the line labelled "a"

• reflection ray

• incident ray

• angle of reflection

• normal

Identify the line that is 90 degrees to a plane mirror

• incident ray

• reflection ray

• normal

• average

The bending of light through different mediums

• reflection

• opaque

• absorption

• refraction

When the refracted light ray bends towards the normal, is it moving faster or slower in the new medium?

• Faster

• Slower

Describe what happens to the speed of light as it moves from the glass into air.

• speeds up

• slows down

• remains constant

The distance between two crests or two troughs of a wave is called:

• frequency
• amplitud
• wavelength
• hertz
