Wavelengths, Frequency and Energy

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

Define wavelength.

Back

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

Front

Define frequency.

Back

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

Front

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

Back

The speed of a wave (v) is calculated using the formula v = frequency (f) × wavelength (λ).

Front

How does energy relate to frequency?

Back

Energy is directly proportional to frequency; higher frequency waves carry more energy.

Front

What happens to the energy of a wave if its frequency doubles?

Back

If the frequency of a wave doubles, its energy also doubles.

Front

What is the wavelength of a wave with a frequency of 1 Hz?

Back

The wavelength of a wave with a frequency of 1 Hz is 299,792,458 meters (the speed of light in a vacuum).

Front

What type of waves have short wavelengths?

Back

Electromagnetic waves, such as gamma rays and X-rays, have short wavelengths.

Front

What is the wavelength of a wave with a frequency of 3 x 10^8 Hz?

Back

The wavelength is 1 meter (using the speed of light, v = f × λ).

Front

What is the frequency of a wave with a wavelength of 500 nm?

Back

The frequency is approximately 6 x 10^14 Hz (using the speed of light, v = f × λ).
