Problem: Calculate the energy of the violet light emitted by a hydrogen atom with a wavelength of 410.1 nm.

FREE Expert Solution

Violet light is a part of the visible portion of the electromagnetic spectrum.


The energy and frequency of electromagnetic waves are related by this equation.


null


Where,

E = energy

h = Planck’s constant

𝜈 = frequency


The relation between the speed of light, it frequency and wavelength is:


null


Where,

c = speed of light

λ = wavelength

𝜈 = frequency


Isolating 𝜈 and placing it in the first equation.
