Wave characteristics

What is a wave?

• A stationary object that does not move

• A repeating disturbance that carries energy from one point to another

• A solid object that blocks energy

• A type of sound that cannot travel through air

What is the highest part of a wave called?

• Trough

• Crest

• Medium

• Shore

Which type of wave does not need a medium to travel?

• Sound wave

• Water wave

• Seismic wave

• Electromagnetic wave

What happens to a wave when it hits the shore?

• It speeds up

• It stops and breaks with a roar

• It becomes invisible

• It travels faster through the air

What is the frequency of a wave?

• The number of crests per minute that pass a point

• The distance between successive crests

• The height of the wave

• The speed of the wave

How does the wavelength of a high-frequency wave compare to a low-frequency wave?

• It is shorter

• It is longer

• It is the same

• It varies randomly

What happens to the leaf on the pond when a frog jumps into the water?

• It sinks

• It floats without moving

• It rises and falls with the waves

• It moves to the edge of the pond

What is the amplitude of an ocean wave?

• The distance from the crest to the trough

• The distance from the flat, undisturbed water level to the highest point

• The height of the wave

• The length of the wave

How does the amplitude of a wave relate to its energy?

• Greater amplitude means less energy

• Greater amplitude means more energy

• Amplitude does not affect energy

• Amplitude and energy are inversely related

In a rope wave, what does the amplitude represent?

• The length of the rope

• The height of a crest above the resting position

• The speed of the wave

• The distance between two crests
