  1. How do you calculate the frequency of light if you know its wavelength ...

    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 make …

  2. Question #39e52 - Socratic

    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 that the …

  3. Question #74da7 - Socratic

    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; lamda = h/p …

  4. Question #ec9fc - Socratic

    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, phase of light #v# …

  5. Lenses are engineered to have specific focal points. besides the ...

    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 a typical …

  6. Light of frequency 5×10^4 is travelling in a medium of ... - Socratic

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

  7. Question #0a177 + Example - Socratic

    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 Maths of …

  8. Questions asked by - Socratic

    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 5.00*10^4 nm ?

  9. How fast is a wave moving if its six waves go by in a second and its ...

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

  10. Answers created by 1s2s2p - Socratic

    A photon of light with wavelength 700 nm has energy E.A photon of light of what wavelength would correspond to energy 2E? How do you find the zeros, if any, of #y= -7x^2-x+22#using the quadratic …
