What is the wavelength of a photon that has 4.42 x 10^8 of energy?

λ = 4.5×10⁻³⁴ m

Explanation:

Given data:

Energy of photon = 4.42×10⁸ J

Wavelength of photon = ?

Solution:

Formula:

E = hc/λ

speed of light = c = 3×10⁸ m/s

planck's constant = h = 6.63×10⁻³⁴ Js

Now we will put the values in formula.

4.42×10⁸ J = 6.63×10⁻³⁴ Js ×  3×10⁸ m/s  / λ

λ =   6.63×10⁻³⁴ Js ×  3×10⁸ m/s /  4.42×10⁸ J

λ = 19.89×10⁻²⁶ Jm /  4.42×10⁸ J

λ = 4.5×10⁻³⁴ m
