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.
