Question

how does the amplitude varies with wavwlength???wht is relation between wavelength & amplitude as well as frequency & intensity...??? can any1 tell me how all thsese related to each othr???

Answer 1

There is no relationship between amplitude and wavelength or between frequency and intensity.

\(I\propto A^2\)
Intensity is proportional to the square of the amplitude, meaning the greater the amplitude the more intense the wave, and vice versa.

\(v=f\lambda\) gives the relation between frequency, \(f\) and wavelength, \(\lambda\). Higher frequency = smaller wavelength and vice versa.

Answer 2

if intensity increses thn no photons increases bt photon energy is unchanged bacaz frequency is unchanged.....???i didnt get this
can explain this..!!!!

Answer 3

yes.Your question is unclear

Answer 4

my question is regarding to photoelectric effect......

Answer 5

yes, go on

Answer 6

wavelength is distance betn trough & crust & thn wht is amplitude???

Answer 7

as light intensity increases no of photons increses(does the no of photons means intensity???) bt photon energy (E=hf) unchanged becaz frequency is unchanged??? how to relate no of photons , photon energy & frequecy...???i m confused abt this no of photons energy frequency

Answer 8

as u tell me abt wavlength & amplitude...tell like this abt intensity & frequency........tell me as amplitude increases intensity increases or as frequency increases intensity increases or i dnt no hw to ask u que......are u getting my que??? or shd i explain u???

Answer 9

As the intensity of a light source is increased, the number of photons increases.
(Does the number of photons mean the same thing as intensity?)

Answer 10

does intensity means no of trough & crust increases???

Answer 11

It tru tht for single frquncy light srce, the intnsty dirctly propto no of photons, bt unit not same, the no of photons usually way large 2 be practical. Instead of no of photons, the intensity usually hav unit power per area, so it considr the energy of light rather thn particle count.

If light srce not a specific frequency (energy), then the intensity of ech photon wnt be equivalent. So intensity not exactly propoto the no of photons. But the 2 concepts are closly related.

\[\boxed{}
% It is true that for a single frequency light source, the intensity is directly proportional to the number of photons, but the units are not the same, the number of photons is usually way to large to be of practical use. Instead of using the number of photons, the intensity usually has units of power per area, so it consider the energy of the light rather than the particle count. If the light source is not a specific frequency (energy), then the intensity of each photon wont be equivalent. So intensity is not exactly proportional to the number of photons. But the two concepts are closely related. \]
