NettetThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as. v w = f λ. From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8. NettetIn addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves. The wavelength λ is the distance between adjacent identical parts …

NettetReason 1: Greater frequency means greater velocity of electrons, which will help them to counteract "space charge" and more electrons can reach the anode. Problem 1:Let's say the intensity (W/m²) of the radiation remains the same, and only the frequency increases. NettetIntensity is the number of photons, wavelength is the colour. The Energy of each photon is given by E=hv where E = Energy, h = Planck constant and v is the frequency. The …
