Waves State Test Review

All waves have which 4 major characteristics?

• Wavelength, frequency, amplitude, velocity
• Wavelength, frequency, amplitude, speed
• Wavelength, period, amplitude, velocity
• Crest, trough, frequency, speed

Wavelength measures the distance between:

• Any two points on a wave
• Two consecutive crests
• Two consecutive compressions
• Two identical points on a wave

The higher the frequency of a wave, the _________ its wavelength.

• Higher
• Lower
• Same
• Unrelated

Amplitude Relates to:

• The energy carried by a wave
• The distance a wave travels
• Both A and B
• Neither A nor B

The speed of all light waves is:

• 300 m/s
• 30,000 m/s
• 300,000,000 m/s
• Speed depends on frequency

Why do red and violet light travel at the same speed?

• They have the same frequency
• They have the same wavelength
• They are both forms of light
• The medium does not affect their speed

How is wave energy converted into electrical energy?

• Using generators
• Using solar panels
• Both A and B
• Neither A nor B

The energy output of a wave power system depends on:

• Wave height only
• Wave speed only
• Wave height, speed, wavelength, and water density
• None of the above

In a solar panel, photons knock electrons free from atoms, generating:

• Heat
• Light
• A flow of electricity
• Magnetism

What does "photovoltaic" mean?

• Converting heat to electricity
• Converting sound to electricity
• Converting sunlight to electricity
• Converting waves to electricity
