Show that the wavelength of electromagnetic radiation is equal to the de-Broglie wavelength of its quantum (photon).

Text Solution

Verified by Experts

Wave length of electromagnetic wave of frequency v and velocity C is given by ,
` lambda = C/v rArr lambda C/H xxh/h = (h)/(((hv)/C))= h/p ( :' (hv)/C=p)`
Hence , we can say wavelength of electromagnetic radiation is equal to the de - Brogile wavelength .
