Find the energy of each of the photons which (i) corresponds to light of frequency 3 xx 10^(15)Hz (ii) have wavelength of 0.50 Å

Find the energy of each of the photons which (i) corresponds to light

1.	Find the energy of each of the photons which (i) corresponds to light of frequency 3 xx 10^(15)Hz (ii) have wavelength of 0.50 Å
Answer» Solution :(i) `v = 3 xx 10^(15) Hz, E = hv = (6.626 xx 10^(-34) JS) (3 xx 10^(15) s^(-1)) = 1.988 xx 10^(-18) J` (II) `lamda = 0.50 xx 10^(-10) m, E = hv = H (c)/(lamda) = ((6.626 xx 10^(-34) Js) (3 xx 10^(15)s^(-1)))/(0.50 xx 10^(-10) s) J = 3.98 xx 10^(-15) J`
