C/C: Gr 4 Wavelength and Amplitude

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its crest or trough.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points on a wave, such as crest to crest or trough to trough.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

How does wavelength affect wave behavior?

Back

Longer wavelengths generally mean lower frequency and lower energy, while shorter wavelengths mean higher frequency and higher energy.

Front

What happens to amplitude when energy increases?

Back

When energy increases, the amplitude of the wave also increases.

Front

What is the relationship between amplitude and sound volume?

Back

Higher amplitude means louder sound, while lower amplitude means softer sound.

Front

What is the relationship between wavelength and pitch?

Back

Longer wavelengths produce lower pitches, while shorter wavelengths produce higher pitches.

Front

What type of wave has a long wavelength and low amplitude?

Back

Ocean waves often have long wavelengths and low amplitudes, making them safer for sailing.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.
