Does intensity depend on frequency
WebYes, the speed of propagation depends upon the wavelength of the wave, and wavelength changes as the frequency changes. No, the speed of propagation depends only on the … 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.
Does intensity depend on frequency
Did you know?
Web5. Yes, the intensity depends, in part, on the frequency. Intensity is power per unit area. Power is energy per time. For a photon, the energy is h ν. So, the intensity will be. I = N h ν / A. if N is the monochromatic photon emission rate (photons per second), ν is the … 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. Two waves can have the same frequency and velocity of prop...
WebSep 22, 2024 · The electric field of the radiation can interact with the molecules's oscillating dipole and only if the frequency is very, very close to that of the vibration energy can be transferred from the radiation to the molecule. ... The electric field squared is proportional to the light intensity; no light no absorption, obviously. WebFeb 20, 2024 · vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in Figure 17.2.2. The frequency is the same as that of the source and is the number of waves that pass a …
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), WebMar 26, 2024 · Does intensity depend on energy? The energy effects of a wave depend on time as well as amplitude. The definition of intensity is valid for any energy in transit, including that carried by waves. ... The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle). The higher the frequency, the …
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.
WebAnswer (1 of 2): The amplitude of a wave is the maximum amount of displacement a particle experiences in a wave. The intensity of a wave is the amount of power the wave transferres per surface area. If consider that wavewave propagates through an 3D space that means the particles don't particul... buy a folding camperWebJun 28, 2024 · Does intensity increase with frequency? (b) The number of electrons emitted per second (i.e. the electric current) is independent of frequency and increases linearly with the light intensity. The number of electrons ejected therefore depends upon the number of photons, i.e. the intensity of the light. Does intensity depend on … buy a folding step stoolceil math c++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. ceil lightWebFeb 20, 2024 · The intensity goes up by a factor of 4 when the amplitude doubles. This answer is a little disquieting.
