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 waves?

Back

Energy refers to the capacity of a wave to do work, which is directly proportional to its frequency.

Front

What happens to energy as frequency increases?

Back

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

Front

What color corresponds to a wavelength of approximately 720 nanometers?

Back

Red.

Front

Which type of electromagnetic radiation has the highest energy?

Back

Gamma radiation.

Front

What is the formula to calculate wavelength?

Back

Wavelength (λ) = Speed of Light (c) / Frequency (f).

Front

If a wave has a frequency of 2 Hz, what is its wavelength if the speed of light is 3.00 x 10^8 m/s?

Back

Wavelength = 3.00 x 10^8 m/s / 2 Hz = 1.5 x 10^8 m.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 3.00 x 10^8 m/s.
