WAVES 4th GRADE

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

What does the term 'wavelength' refer to in wave properties?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How is frequency defined in the context of waves?

Back

Frequency is the number of waves that pass a point in a given amount of time, usually measured in hertz (Hz).

Front

What happens to the amplitude of a wave when it carries more energy?

Back

The amplitude increases when a wave carries more energy.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the formula to calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Wavelength x Frequency.

Front

What is the difference between mechanical waves and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel through, while electromagnetic waves can travel through a vacuum.

Front

Can sound travel in a vacuum? Why or why not?

Back

No, sound cannot travel in a vacuum because it requires a medium (like air) to carry the sound waves.
