Depends on what you've been given to find it with.
But typically we use an oscilloscope to convert the wave into an electrical signal and then display that signal on a screen. That display will be the shape of the wave. So we can actually see and physically measure the amplitude which is simply the maximum displacement of the wave from its zero or neutral position.
If you're talking about finding A in a physics problem, a typical wave function looks like y = A sin(kx - theta + phi) where theta = omega*T is the current angle of the wave at time T when going omega radians per second rotation through the wave length. Phi is a fixed offset (the phase) that marks the position of the wave form when T = 0. kx indicates the XX axis where the wave height y is measured (typically x = 0). Note that all angles here are in radians.
And there you are A = y/sin(- theta + phi) to solve for the amplitude at any time T and position x = 0. y is the current wave height at T.
What else can I help you with?
How does an increase in intensity change the amplitude?
An increase in intensity of a wave causes the amplitude to increase as well. This is because intensity is directly proportional to the square of the amplitude of the wave. So, as intensity increases, the amplitude of the wave also increases.
Does increase in amplitude effect energy?
Yes, increasing the amplitude of a wave does affect its energy. Energy is directly proportional to the square of the amplitude of a wave. This means that doubling the amplitude of a wave will increase its energy by a factor of four.
As you increase the amplitude of the wave you also can increase the what?
As you increase the amplitude of a wave, you can also increase its energy. This is because the amplitude of a wave determines the maximum displacement of a particle from its equilibrium position, which correlates with the amount of energy transferred by the wave.
How does the amplitude affect the energy of a wave?
The intensity will increase if the energy increase. The intensity is proportional to the square of the amplitude of a wave.
Does intensity increase with the amplitude of a sound wave?
Yes, generally, intensity does increase with the amplitude of a sound wave. The intensity of a sound wave is directly proportional to the square of its amplitude. This means that if the amplitude doubles, the intensity will increase by a factor of four.
What differences will you hear in a sound if there is increase in the amplitude?
The amplitude of a sound corresponds to its loudness so an increase in amplitude will correspond to a louder sound.

How would the wavelength and amplitude of a wave be affected by an increase or decrease in energy?
An increase in energy would generally lead to a decrease in wavelength and an increase in amplitude for a wave. Conversely, a decrease in energy would result in an increase in wavelength and a decrease in amplitude. This is because energy is directly related to the frequency and intensity of a wave, which in turn impacts its wavelength and amplitude.
What property of a wave increase as the wave energy increase?
An increase in energy corresponds to an increase in frequency or a decrease in wavelength.
How do you increase the amplitude of a longitudinal wave?
You can increase the amplitude of a longitudinal wave by increasing the energy or force that is causing the wave to propagate. This will result in higher density or compression regions in the wave, which increases its amplitude.
What happens to the wave and the color of the wave when you increase or decrease the amplitude?
You seem to be talking about a light wave. If you increase the amplitude the light gets brighter, and if you decrease it gets dimmer. Amplitude has no effect on colour.
