What is the wavelength λ of the photon that has been released in Part B?

ΔE = | −2.04×10^{−18} J |

The energy of the photon emitted by the electron is related to its wavelength by

E=hcλ

where λ is the wavelength in meters, 6.626×10^{−34} J⋅s is Planck's constant, and 3.00×10^{8} m/s is the speed of light in a vacuum.

Step 1

The relation between energy and wavelength of a radiation is given by Planck-Einstein’s relation, stated below as expression (1); where, E is the energy, h is the Planck’s constant, c is the speed of light, and λ is the wavelength.

Step 2

The negative sign of energy in -2.04 × 10-18 J signifies that the energy is released in the process. In order to calculate the wavelength of the photon, the mode...
