May 17, 2018 · What is the formula for the intensity of light, and how are amplitude, frequency and number of photons considered? Ask Question Asked 7 years, 7 months ago Modified 3 years, …

Jul 14, 2018 · The term "intensity" has many meanings, and can be misleading depending on who interprets the word. Intensity here probably is intended to mean energy intensity- as in how …

Nov 22, 2018 · Light energy relates to its wavelength and momentum too. However, if we treat light as a particle what will be the relation between its intensity to its wavelength?

Dec 12, 2024 · For a plane wave of the form E =E0 cos(ωt − kz) E = E 0 cos (ω t k z), the intensity is I = 12cϵ0E20 I = 1 2 c ϵ 0 E 0 2. This can be derived by noting that I = S I = S , …

Jun 16, 2016 · In general you're right - an electron being subject to interactions with more than a single photon may have a higher kinetic energy. However, in the vast majority of photoelectric …

When unpolarized light is polarized with two polarizers, the intensity becomes I =I0cos2(θ) I = I 0 cos 2 (θ) (Malus's law). But when unpolarized light is polarized with only one polarizer, the …

May 5, 2023 · The intensity of a single light ray doesn't make sense because a ray is a direction of travel. But it's perfectly possible to give the intensity of reflected light from P passing the …

Oct 19, 2020 · Is the intensity or brightness of light the same idea? In other words, when we are observing Malus's law, are we looking at the "brightness" of light? If they are not the same …

Dec 5, 2020 · Intensity is energy per area per time. Thus, it certainly does not only depend on the number of photons. Just take the same number of photons, but change their individual energy …

If the incident light is unpolarized and a vertical polarizer is present, this will add a factor of 1 2 1 2 in front of this answer to get a transmission of I0 8 I 0 8 (I0 I 0 being the incident intensity on …
