Wavelength, Frequency, and Energy

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

What is frequency?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is energy in the context of electromagnetic waves?

Back

Energy is the capacity to do work, and in electromagnetic waves, it is directly proportional to frequency.

Front

What happens to energy as frequency increases?

Back

As frequency increases, the energy of the wave also increases.

Front

Which electromagnetic waves have the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

Which electromagnetic waves have the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What happens to wavelength when frequency decreases?

Back

When frequency decreases, the wavelength increases.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.

Front

How do you calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Wavelength x Frequency.
