Does intensity depend on frequency

WebJul 7, 2024 · 2 Answers. Yes, the intensity depends, in part, on the frequency. If the only thing one changes is the frequency of the photons, then doubling the frequency will double the intensity. Alternately, doubling only the emission rate, or focusing the photons to hit half the area will also double the intensity. Does frequency affect light intensity? WebSince wave frequency is the number of waves per second, and the period is essentially the number of seconds per wave, the relationship between frequency and period is. f = 1 T. 13.1. or. T = 1 f, 13.2. just as in the case of harmonic motion of an object.

WebApr 6, 2024 · This means that the intensity of a wave depends on the amplitude of the wave. Since light is also a wave, its intensity will depend on the amplitude of the wave. So, the correct answer is “Option A”. Note: The frequency of the light influences the energy per photon. The energy per photon is given as E = h f …. (i), WebAnswer: It really depends on what kind of waves you are talking about. For most physical waves that propagate through a medium (sound waves through the air, water waves through water, etc.) intensity depends on the amplitude of the wave.

WebSep 29, 2024 · If intensity of a wave is proportional to frequency, why doesn’t sound level, in general, depend on frequency. i.e. Higher frequency, higher intensity, higher sound level. Why is this not the case? For example if you change the frequency of a sound wave from 500Hz to 15000Hz, this won’t necessarily be perceived as a change in loudness. WebDec 15, 2024 · The kinetic energy depends only on the frequency on the light, and hence the energy provided by each photon. This suggests that the photoelectric effect involves one electron and only one photon. ... On the other hand, the stopping voltage does not depend on the intensity of the light (provided the light's frequency is kept fixed.) Mathematical ...

WebSince loudness varies with frequency as well as intensity, a special unit has been designed for loudness — the phon. One phon is the loudness of a 1 dB, 1,000 Hz sound; 10 phon is the loudness of a 10 dB, 1,000 Hz sound; and so on. Cupping ones hand behind one's ear will result in an intensity increase of 6 to 8 dB.
