WebI was seeing the proof of the de broglie wavelength. He equated E=mc^2 and E=hf. Then, hf=mc^2 If I'm not crossing a line, if we separate the constants to one side and the variables to the other, we get: f/m=c^2/h which is a constant. What does that even mean? Is f/m always a constant? #Sorry to have posted this doubt again. :-) • ( 4 votes) WebWavelength is inversely proportional to energy but frequency is directly proportional as shown by Planck's formula, \(E=h u\). Spectroscopists often talk about energy and frequency as equivalent. The cm-1 unit is particularly convenient. The infrared range is roughly 200 - 5,000 cm-1-1 and the UV between 25,000 and 100,000 cm-1.
WebSep 12, 2024 · Figure 4.2.2: Single-slit diffraction pattern. (a) Monochromatic light passing through a single slit has a central maximum and many smaller and dimmer maxima on either side. The central maximum is six times higher than shown. (b) The diagram shows the bright central maximum, and the dimmer and thinner maxima on either side. WebMay 15, 2024 · So, the wavelength of a light wave is given as; λ = Where λ is the wavelength of light c is the velocity of light and f is the frequency of the light The energy of a photon is given as, E = h × f = Where E is the energy of a photon h is the Planck’s constant i.e., h = 6.64 × 10 -34 joule-second
WebMar 27, 2024 · 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 can find the energy of the photon with Planck's formula: E = h × f; where h is the Planck's constant: h = 6.62607015E-34 m² ...
