Question

The number of photons of light having wavelength 100nm which can provide 1.00j energy is nearly?

Answer 1

E=n×h×c/wavelength
n=E×wavelength/hc
n=(1×100×10^-9)/(6.63×10^-34×3×10^8)
n=5.027×10^17.no.of photons are required.

Answer 2

Explanation:

E=n×h×c/wavelength

n=E×wavelength/hc

n=(1×100×10^-9)/(6.63×10^-34×3×10^8)

n=5.027×10^17.no.of photons are required.
