# How are wavelength and energy related directly or inversely?

s is called Planck's constant. Since the energy goes up as the frequency increases, the energy is directly proportional to the frequency. Because frequency and wavelength are related by a constant (c) the energy can also be written in terms of wavelength: E = h. That is, energy in inversely proportional to wavelength.

Just so, what is the formula for wavelength?

Wavelength is the distance between the crests of a wave. Wavelength is represented with the Greek letter lambda: λ. It is equal to the velocity of the wave, divided by the frequency.

How is energy related to wavelength?

The greater the energy, the larger the frequency and the shorter (smaller) the wavelength. Given the relationship between wavelength and frequency — the higher the frequency, the shorter the wavelength — it follows that short wavelengths are more energetic than long wavelengths.

How do you calculate the wavelength of a wave?

If you want to calculate the wavelength of a wave, then all you have to do is plug the wave's speed and wave's frequency into the equation. Dividing speed by frequency gives you the wavelength. For example: Find the wavelength of a wave traveling at 20 m/s at a frequency of 5 Hz.
