Light Waves

The lowest part of the wave is?

• crest
• trough
• rarefaction
• wavelength

The highest point on a wave

• trough
• amplitude
• crest
• wavelength

The distance between the line of origin to the top of the wave is called

• amplitude
• wavelength
• frequency
• speed

The bending of a wave as it travels from one medium to another and as a result changes speed is called

• reflection
• refraction
• diffraction
• interference

What word describes the number of waves that pass a certain point in a given amount of time?

• rarefactions
• amplitude
• resonance
• frequency

The bending of a wave around the edge of a barrier is called

• reflection
• diffraction 
• interference
• refraction

The bouncing back of a wave when it hits a surface through which it can NOT pass is called —

• rarefaction
• reflection
• diffraction
• refraction

When a wave moves parallel to the direction that the wave travels, it is a

• longitudinal
• transverse

Which electromagnetic wave has the shortest wavelength?

• gamma
• visible

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

• absorbed
• stopped
• reflected
• refracted
