Find energy of each of the photon which
(I ) Correspond to light of frequency `3xx 10^(15) Hz`
(ii) have wavelength of 0.50 A

Text Solution

Verified by Experts

(i) `3xx 10^(15) Hz` frequency of light
E=-hv
`= (6.626 xx 10^(34) J s ) (3 xx 10^(15) s^(-1))`
(ii) wave energy of 0.50 A
E=hv = `(hc )/( lambda) `
`=((6.626 xx 10^(34) J s)(3.0 xx 10^(8) ms^(1)))/( 0.50 xx 10^(10) m)`
So `0.50 A E= 3.98 `xx 10^(15)`
