Question

calculate and compare the energies of 2 radiations one with a wavelength of 400nm and other with 800nm.

Answer 1

λ₁ = 400 nm.

λ₂ = 800 nm.

Now, we know the formula,

E₁/E₂ = λ₂ /λ₁

= 800/400

= 2/1

∴ Ratio of the Energies = 2 : 1.

Hope it helps.

Answer 2

Explanation:

,

E₁/E₂ = λ₂ /λ₁

= 800/400

= 2

∴ Ratio of the Energies = 2 : 1.
