📕 Unit 3 Assessment Waves & Radiation

Front

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

Back

Speed = Frequency × Wavelength

Front

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

Back

As frequency increases, wavelength decreases.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What happens to the energy of an electromagnetic wave as its frequency increases?

Back

The energy of the wave increases.

Front

What is the speed of a wave with a frequency of 50 Hz and a wavelength of 10 m?

Back

500 m/s

Front

What does a wave carry?

Back

Energy.

Front

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

Back

Higher energy corresponds to shorter wavelengths.

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What are electromagnetic waves?

Back

Waves that can travel through a vacuum and do not require a medium, such as light waves.

Front

What is the unit of measurement for wavelength?

Back

Meters (m).
