Waves Test Review

Which of the following describes the height of a transverse wave?

• frequency

• trough

• crest

• amplitude

Xrays and Gamma Rays have the highest frequencies, therefore, highest energies.

• True

• False

How are Electromagnetic waves different from Mechanical waves?

• EM waves have very short wavelengths

• EM waves transmit energy instead of matter

• EM waves can travel through the vacuum of space (without particles)

• EM waves can change direction by reflection

Which of the following electromagnetic waves has the lowest frequency?

• gamma ray

• infrared wave

• visible light wave

• microwave

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern

The _______________ determines the color of visible light.

• wavelength (and frequency)

• speed

• amplitude

• particles of the medium

To calculate the frequency of an electromagnetic wave, you need to know the speed of the wave and its

• wavelength.

• intensity.

• refraction.

• amplitude.

Which of the following occurs as a light wave bends when it passes from one medium into another?

• constructive interference

• refraction

• destructive interference

• reflection

Which type of wave has a wave perpedicular to the disturbance?

• surface
• mechanical
• transverse
• longitudinal

Which is true of a mechanical wave?

• It must have a medium
• It must travel in empty space.
• It can travel in a vacuum.
• Both sound and light are examples.
