Wave Energy Quiz

What does a wave carry from one place to another?

• Water

• Energy

• Air

• Objects

In a water wave, how do the water molecules move?

• Forward and backward

• Side to side

• Up and down

• In a circular motion

What happens to a rubber duck floating on water when a wave passes?

• It moves forward with the wave

• It moves up and down

• It sinks

• It stays completely still

According to the work-energy theorem, the average work done on a floating object by a wave is proportional to what?

• The square of the wave's amplitude

• The wave's wavelength

• The average square of the object's vertical speed

• The frequency of the wave

How does a buoy convert wave energy into electricity?

• The buoy absorbs sunlight and generates power

• A magnet inside moves up and down through a coil, generating a current

• The buoy stores energy in batteries that are charged by the sun

• The buoy moves the water, which turns a turbine

What scientific principle explains how moving a magnet through a coil generates electricity?

• Newton's Laws

• Electromagnetic Induction

• The Law of Thermodynamics

• The Doppler Effect

Which of the following increases the energy of a wave?

• Decreasing its amplitude

• Increasing its amplitude and frequency

• Decreasing its frequency

• Making the water shallower

The total energy in a wave over one wavelength is proportional to which factors?

• Only frequency

• Amplitude squared and frequency squared

• Amplitude squared, frequency squared, and wavelength

• Only wavelength

If you increase the frequency of a wave while keeping the speed constant, what happens to the wavelength?

• It increases

• It decreases

• It stays the same

• It disappears

Why is wave energy useful for electricity generation?

• It is a consistent and renewable energy source

• It requires fossil fuels to function

• It works only in deep oceans

• It produces more pollution than other energy sources
