Since one eV is 1.602 x 10-19Joules, use the above formula and multiply by that factor Joules = 1.986 x 10-23/nm You may recognize the number 1.602 x 10-19as the charge of an electron in Coulombs. How to convert delta microns or nanometers to delta cm-1(inverse cm) ...
To determine which metals will show photoelectric emission when light of wavelength 412.5 nm is incident on them, we need to follow these steps: Step 1: Calculate the energy of the incident photonsThe energy of a photon can be calculated using the formula:E=hcλwhere:- E is the energy of...
KE=1eV 3. Calculate the energy of the incident light: The energy of the incident light can be calculated using the formula: E=hcλ where: - h (Planck's constant) ≈4.14×10−15eV s - c (speed of light) ≈3×108m/s - λ=450nm=450×10−9m Converting hc to eV·nm, we ...

The emission spectrum is the spectrum of frequencies of electromagnetic radiation emitted by a chemical compound due to a transition from a high energy level to a lower level. Each one of the wavelengths λ of the emitted ...
Thus, the minimum spatial resolution was determined to be the smallest half-period that could be resolved with an image modulation of 0.265. Note that another formula exists for determining the image modulation: (Imax(r,θ) − Imin(r,θ))/(Imax(r,θ) + Imin(r,θ)). The ...
Bohr's model was a very insightful model and one of its most important result was the formula for energy of the system. According to the model, the energy of a single electron system with atomic number {eq}Z {/eq} and in its {eq}n {/eq}...
