What is the importance of wavelength in electromagnetic radiation?
Electromagnetic radiation refers to a form of energy emitted and absorbed by charged particles, as it travels through space. This energy travels through out the universe at the speed of light, in the form of waves.
What separates one type of electromagnetic radiation from another is its wavelength.
Wavelength is important because it determines the characteristics of a wave.Longerwavelength waves such as radio waves carry low energy. Shorter wavelength waves such as x-rays, carry higher energy.
Electromagnetic waves fill a spectrum with wavelengths that vary from thousands of kilometres long, down to wavelengths more than 1020 times smaller. The wavelengths that make up visible light comprise only a tiny fraction of this spectrum.
