If The Energy Of A Photon Is Given As Chemistry Question

If the energy of a photon is given as : =3.03 × 10⁻¹⁹J then, the wavelength (λ) of the photon is :

Options

(a) 6.56 nm
(b) 65.6 nm
(c) 656 nm
(d) 0.656 nm

Correct Answer:

656 nm

Explanation:

The energy of photon, E = hc /λ = 3.03 x 10⁻¹⁹ ⇒ λ = (6.626 x 10⁻³⁴ x 3 x 10⁸) / 3.03 x 10⁻¹⁹= 656 nm
