• Wavelength is the distance between two consecutive points on a wave that are in phase.

• The higher the frequency, the shorter the wavelength.

• The lower the frequency, the longer the wavelength.

• The formula to calculate the speed of a wave is wavelength x frequency.

• Examples: Radio waves have a low frequency and long wavelength, while X-rays ha...read more
