find energy of each of the photons which
(i) correspond to light of frequency `3xx 10^(15) Hz`.
(ii) have wavelength of 0.50 A.

Text Solution

Verified by Experts

i. `E=hv=6.6xx10^(-34)xx3xx10^(15)=1.98xx10^(-18)J`
ii. `E=hc/lambda=(6.6xx10^(-34)J sxx3xx10^(8) m s^(-1))/(0.50xx10^(-10)m)`
`=3.98xx10^(-15) J`
