The Energy of a Photon:When an electron falls from the higher energy level {eq}(n_2) {/eq} to the lower energy level {eq}(n_1) {/eq}, a certain amount of energy is released during this transition in a hydrogen-like atom. This certain amount of energy is {eq}...
The maximum kinetic energy KEeof ejected electrons (photoelectrons) is given byKEe= hf − BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material. What is photoelectron kinetic energy? The maximum kinetic energy of a ph...
To calculate the energy of a photon, follow these easy steps: If you know the wavelength, calculate the frequency with the following formula: f =c/ λ where c is the speed of light, f the frequency and λ the wavelength. If you know the frequency, or if you just calculated it, you...
Some Other Forms of Energy The light we see is an electromagnetic phenomenon that has energy by virtue of the vibrations of packets of waves called photons. German physicist Max Planck determined that the energy of a photon is proportional the frequency (f) with which it vibrates, and he cal...

Finally, we must rearrange this substituted formula to get the wavelength in terms of energy: λ=h×cEλ=Eh×c How do I calculate wavelength from energy? To calculate wavelength from the energy of a photon: Convert the photon's energy into joules. Divide the speed of light, equal to 299...
The kinetic energy (KE) of the ejected electron can be calculated using the equation: KE=Ephoton−Φ Substituting the values: KE=4.5eV−3.0eV=1.5eV Step 2: Calculate the de Broglie WavelengthThe de Broglie wavelength (λ) can be calculated using the formula: λ=h√2m⋅KE However, ...
The wavelength of the photon is inversely proportional to its frequency. The relationship between them is given by the following formula, (wavelength)λ = (velocity of light)c (frequency)ν Frequency: It denotes the number of waves passes in given amount...
