Understanding Waves and Energy Transfer

Front

What are electromagnetic (EM) waves made up of?

Back

Changing electric fields and magnetic fields.

Front

What is the term for the number of wavelengths that pass a point in one second?

Back

Frequency.

Front

What happens to the wavelength of an EM wave as the temperature of the material increases?

Back

It gets shorter.

Front

What type of waves are electromagnetic waves?

Back

Transverse waves.

Front

What does it mean to transmit?

Back

To send from one place to another.

Front

What is the definition of wavelength?

Back

The distance between successive crests of a wave.

Front

What is amplitude in the context of waves?

Back

The maximum extent of a wave's oscillation, measured from the rest position.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

As frequency increases, wavelength decreases.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Approximately 299,792 kilometers per second (the speed of light).

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel to the direction of wave travel.
