Energy of photon, E = hν = h(c/λ) = 3.374 x 10-19 J
[It is known that, h = 6.626 x 10-34m2 kg/s and c = 3 x 108 m/s]
Number of photons emitted by the sodium lamp in one second = [60 / 3.374 x 10-19]
∴ The number of photons emitted by the sodium lamp in 10 hours is
= [(60 x 10 x 3600)/ (3.374 x 10-19)] = 6.4 x 1024
pls give me a brainlist answer
