Wavelength,+Frequency+and+Energy

 * Understand the inverse relationship between wavelength and frequency, and the direct relationship between energy and frequency.

Light is a wave.


A wave has a crest (highest point) and a trough (lowest point). Waves have a wavelength (Lambda) that is measured from crest to crest. Waves have a frequency (the number of waves that pass a point in a given time period) A low frequency means low energy. A high frequency means high energy. Waves with a long wavelenghth have a low frequency... and are low in energy. Waves with a short wavelengh have a high frequency... and are high in energy.
