Find energy of each of the photons which (i) correspond to light of frequency 3×1015 Hz. (ii) have wavelength of 0.50 Å.





Q.6:- Find energy of each of the photons which
(i) correspond to light of frequency 3×1015 Hz.
(ii) have wavelength of 0.50 Å.

 

Answer:-
(i) ν = 3×1015 Hz
E = hν = (6.626×10-34 Js)×(3×1015 s-1) = 1.988×10-18 J
(ii) λ = 0.50×10-10 m
 E = hν = hc/λ = (6.626×10-34 Js)×(3×1015 s-1)/0.50×10-10 m = 3.98×10-15 J
