The energy of an X-ray photon having wavelength of 3 x 10⁻¹⁰?

Explanation

The energy (E) of a photon is given by:

E = hc/λ

where h is Planck's constant (6.63 x 10⁻³⁴ J s), c is the speed of light (3 x 10⁸ m/s), and λ is the wavelength.

E = (6.63 x 10⁻³⁴) * (3 x 10⁸) / (3 x 10⁻¹⁰) = 6.63 x 10⁻¹⁶ J
