Bill Nye - Waves

Front

What does the length of the wavelength depend on?

Back

The length of the wavelength depends on the speed of the wave.

Front

How do you measure a wavelength?

Back

You measure a wavelength from crest to crest.

Front

What causes an echo?

Back

An echo is caused when a sound wave bounces off of an object.

Front

What is the amplitude of a wave?

Back

The amplitude of the wave is simply the height of the wave.

Front

How do air molecules transmit sound waves?

Back

When sound waves travel through the air, the air molecules must bump into each other to transmit sound.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves and electromagnetic waves.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the direction of the wave, while in longitudinal waves, the particle movement is parallel to the direction of the wave.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.
