Calculate the mass of a photon with wavelength 3.6 Å |
|
Answer» Solution :Here, `lamda = 3.6 Å = 3.6 xx 10^(-10)m` As photon travels with the VELOCITY of light, `v = 3.0 xx 10^(8) MS^(-1)` By de Broglie equation, `lamda = (h)/(MV) or m = (h)/(lamda v) = (6.626 xx 10^(-34)JS)/((3.6 xx 10^(-10)m) (3.0 xx 10^(8) ms^(-1))) = 6.135 xx 10^(-29) kg` |
