Sriman Dutta Posted December 17, 2016 Posted December 17, 2016 Hello, If there's a wave having velocity v, such that in time t, it has travelled a distance of x, then will the equation relating v and x be v=kx/t, where k is its wavenumber.
DevilSolution Posted December 17, 2016 Posted December 17, 2016 Hello, If there's a wave having velocity v, such that in time t, it has travelled a distance of x, then will the equation relating v and x be v=kx/t, where k is its wavenumber. EMR is constant. What do you mean by wavenumber? a wave has a frequency, amplitude, length and phase
Country Boy Posted December 17, 2016 Posted December 17, 2016 What do you mean by "EMR" (I would have thought "electro-magnetic radiation" or "resonance" but those aren't numbers.) Ther was no mention of "EMR" in the original post. The "wave number" is the reciprocal of wavelengh- The number of wave crests per unit length.
Sriman Dutta Posted December 17, 2016 Author Posted December 17, 2016 I am really unknown of this term EMR. A more detailed explanation will be helpful.
andrewcellini Posted December 17, 2016 Posted December 17, 2016 (edited) What do you mean by wavenumber? wavenumber in this context is given by 1/λ assuming the op means v is frequency rather than velocity otherwise he just "redefined" velocity by accident. Edited December 17, 2016 by andrewcellini
DevilSolution Posted December 17, 2016 Posted December 17, 2016 (edited) I am really unknown of this term EMR. A more detailed explanation will be helpful. Electromagetic Radiation covers the electromagnetic spectrum for all waves, light, microwaves, infrared, ultraviolet etc all travel at the SOL (speed of light). Other than sound and gravity im not sure what else has wave form, other than electrons in QM. Here's a link to better explain it than me. https://en.wikipedia.org/wiki/Electromagnetic_radiation you can create your own waveforms ofcourse and things like the harmonic series. I just assumed you were referring to EM waves. Edited December 17, 2016 by DevilSolution
