what is the energy in joules of one photon of x-ray radiation with a wavelength of 0.120 nm?

Sagot :

The energy of one photon of x-ray radiation with a wavelength of 0.120 nm is 1.65 × 10⁻¹⁵ Joule.

What is photon energy?

The energy that a single photon carries is known as photon energy. Energy is inversely correlated with wavelength because it is directly proportional to the electromagnetic frequency of the photon.

Given that wavelength of photon is 0.120 nm.

Then, energy of photon is= hc/λ

= (6.6×10⁻³⁴×3×10⁸)/(0.120×10⁻⁹ Joule.

= 1.65 × 10⁻¹⁵ Joule.

Hence, the energy of photon is 1.65 × 10⁻¹⁵ Joule.
