Feb 15, 2016 · For light: frequency = c / lambda speed of propagation of a wave = wavelength x frequency speed of propagation of light in a vacuum = c ~= 3 times 10^8 ms^-1 Rearranging to …

Apr 8, 2017 · The energy of a photon is given by the following equation. aaaaaaaaaaaaaEquation (a) E = h ⋅ f Where h = Planck's constant(6.62 ⋅ 10−34J ⋅ s) f = frequency(1 s) Since we know …

Note that for a photon, v=c. E = p/c c^2 E = pc Now we just need to find the momentum of a photon. In a relativistic frame, particles have a wavelength given by the de Broglie wavelength; …

We also see from above equation (1) that with change in wavelength associated with light, its frequency changes. Larger wavelength will have smaller frequency and vice-versa. However, …

The refractive index depends primarily on the material of the lens. However, even for an given material, the refractive index does depend on the frequency of light - albeit rather weakly. For …

Light of frequency 5×10^4 is travelling in a medium of refractive index 1.5. What is the wavelength? Physics

Standing waves in strings with both ends fixed have a node at each end of the string. Simply "fill in" the pattern to find the number of nodes for each frequency . The fundamental goes: N-A-N …

There is an important relationship between frequency, f and wavelength, l you should know, which is that they are linked with the speed of the wave, v in that medium: v (m/s) = f (Hz) x l (m) The …

The wavelength of the green light from a traffic signal is centred at 522 nm. What is the frequency, v, in Hz, of this radiation? How to calculate the energy, in joules, of a photon of wavelength …

Explanation: The question states 6 waves go by per second, that's the definition of frequency. So f = #6 s^-1# or 6 Hertz.
