# Smallest wavelenghth?

Wavelengths vary over many orders of magnitude; AM radio is about 300 meter wavelength, FM about 3 m, 1 GHz about 30 cm, infrared about 1 to 100 microns, red light about 600 nanometers, blue light about 400 nanometers, etc.

As above...red light about 600 nanometers, blue light about 400 nanometers, so what could the smallest possible wavelength of light be or is it infinely small?

or the longest possible wavelength for that matter

Do you mean the smallest wavelength of visible light or any type?

Gamma rays have the shortest wavelengths of any other type of electromagnetism. They can have wavelengths of less than 10 picometre.

On the other hand, Extremely low frequency is abought $$\lambda$$=100Mm

You might say that the smallest wavelength possible would be http://en.wikipedia.org/wiki/Planck_length" [Broken] (1.616e-35 metres) which is the smallest distance predicted before quantum effects reduce spacetime to a quantum foam.

Could the smallest/longest wavelength be ascosciated with zero point energy?

$$\lambda_0=\sqrt{\frac{1+\frac{v}{c}}{1-\frac{v}{c}}}\lambda_s$$
