What is a wavelength?

Back

The distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

Front

How does amplitude affect sound?

Back

Amplitude determines the loudness of a sound; higher amplitude means louder sound.

Front

What is the difference between pitch and frequency?

Back

Pitch is how high or low a sound seems, while frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.

Front

Why can't sound travel in outer space?

Back

Sound requires a medium to travel through; in outer space, there is no medium.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium to travel through, such as sound waves.

Front

What is the difference between a crest and a trough?

Back

A crest is the highest point of a wave, while a trough is the lowest point.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, consisting of different colors.
