Electromagnetic Spectrum

The electromagnetic spectrum extends from high frequency or high energy (short wavelength 10-15m) waves, e.g gamma rays to low frequency , low energy (long wavelength 10tothe4m) waves e.g radio waves

Visable light is one type pf electromagnetic radiation.and is the only part of the electriomagnetic spectrum that can be seen with the eye. it consists of the colours from red to violet.

All waves can be described in terms of their amplitude,frequency and wavelength. The wavelength is simply the distance between teo succsessive peaks in…
