Question

Calculate the frequency and wavelength of photon with energy 3.98×(10)-7

Answer 1

Explanation:

E=h×n

where E=energy

h is the plank constant=6.623×10^-34(si unit)

and n is the frequency.

so n=E÷h

=6.01×10^18 hz

again we know C=n×L

where C is the velocity of light (photon)=3×10^8 m/sec

L is the wavelength.

so, L=C÷n

=4.99×10^-11 m
