It turns out that all phenomena (such as sound or light) which obey the wave-equation obey a very similar formula. The primary difference in going from waves on a string to any other type of wave is that the constant (which measures the tension of the string) is replaced by some other constant characterizing the medium of propagation for the waves. If we consider traveling sinusoidal waves, then the solution will have the general form . Then, using Eq. 1 we will find a result of the following form for the power. (Here, indicates the average value of the quantity q.)
Note that, at any instant in time t, the power may be different: it varies with the oscillations of . This is why we define intensity as the time average of the arriving power. Finally, because the time average of or is just 1/2, we have
Note that in the last line we replaced the factor with a general proportionality constant . We do this because for waves which are not waves on a string, we end up with factors other than to describe the medium of propagation. What is the same for all types of waves, the main point here, is that the intensityis proportional to the square of the amplitude.
Not sure what formula you are looking for. Wave intensity is given by the amplitude of the wave.
Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula; I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity. So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.
Amplitude and wavelength are independent of each other. There is no such formula.
-- Speed of a wave = (frequency) times (wavelength) -- There is no general formula for amplitude.

Actually the amplitude depends on your modulator by which you generated your signal you can pick any amplitude you want but here is the formula for frequency modulated signal: Ac here decide the amplitude of the signal and you can see that it is not related to the frequency component of your signal.

if you are studying a (simple) wave described by: x = A sin(kt) then A = amplitude
E = hc/l
Cp-Cv is the relation of Mayer's formula. It can also be defined in words as the difference between two specific heat capacities.
the formula showing the relation between the unit of any physical quantity n the unit of fundamental physical quantity is called dimensional formula.........of dat quantity
By definition Pi is the relation between the radius and circumference of a circle.
Wave length*2 dvided by number of waves Amplitude is the vertical distance (from crest to trough) divided by 2
