The energy of a photon with a wavelength of 245 nm will be 8.08 ×10⁻¹⁹ J. De Broglie relation is used to find out the energy.
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The relationship between the wave's wavelength,energy is;
[tex]\rm E = \frac{hc }{\lambda} \\\\ \rm E = \frac{6.6 \times 10^{-34} \times 3 \times 10^8}{245 \times 10^{-9}} \\\\ \rm E=8.08 \times 10^{-19}\ J[/tex]
Hence, the energy of a photon will be 8.08 ×10⁻¹⁹ J.
