what is amplitude.....
Answers
Answer:
The maximum displacement of the particles of the medium from their original and disturbed position when the wave passes through the medium is called amplitude of a wave.
the amplitude of a wave is the same as the amplitude of the vibrating body producing the wave.
Ripples in water, sound traveling in air, and coordinated vibrations of objects are examples of waves you have probably encountered in your life. A good way to visualize a wave is to insert the end of a pencil into a container of still water. The surface of the water is disturbed, producing ripples, or waves.
Electromagnetic waves, such as light, radio waves, microwaves, and x-rays, are special waves that do not require a medium for propagation. We cannot see or hear these waves, but they exist in nature and in many of the products we use every day.
Regardless of the kind, every wave has an amplitude. Amplitude is the maximum displacement of points on a wave, which you can think of as the degree or intensity of change. This maximum displacement is measured from the equilibrium position. The following picture shows a diagram of a sine wave. The diagram shows amplitude and wavelength, which is the distance between two successive like points on a wave. Wavelength is like the distance between two adjacent peaks or two adjacent valleys. Stated another way, wavelength is the time required to complete one full cycle of the wave.
The equilibrium position is the straight line represented by the x-axis. It represents the shape of the medium when there is no wave, or when the water is still and undisturbed in the case of ripples in water. This helps us see another way to state the definition of amplitude, which is the vertical distance from a peak to the equilibrium position or from the equilibrium position to a valley. Amplitude is used to describe the peak value of such quantities as the level of sound waves, and power and voltage in electrical and electronic systems.
