Question

The energy E of a photon and its wavelength are related by E λ =X. What is the numerical value of X. (h=6.63*10^-34Js; c=3*10^8m/s) (10 pts)

Answer 1

19.89×10^-26Jm

Step-by-step explanation:

The Energy of a photon is given as;

E = h×c/λ

Where h is Plank's constant.

c is speed of light

λ is the wavelength.

By multiplying both sides of the equation to λ

E × λ = h×c/λ × λ

E × λ = h×c

= 6.63×10^-34× 3×10^8

= 19.89×10^-26Jm
