Effect of Frequency and Amplitude on Sound
A sound wave with a shorter wavelength has a higher frequency, which means it has a higher pitch and cycles more quickly. Conversely, a longer wavelength has a lower frequency, resulting in a lower pitch and slower cycles.
For instance, when you pluck a guitar string near its end, it produces a sound with a higher pitch because the string’s vibrations are faster. But when you pluck it near its center, it produces a sound with a lower pitch because the vibrations are slower.

Difference Between Amplitude and Frequency
Amplitude and frequency are fundamental concepts in the study of periodic motion. While both describe characteristics of oscillatory phenomena, they represent distinct aspects of the motion. Amplitude refers to the maximum displacement of a wave or oscillating object from its equilibrium position that reflects its intensity or strength. On the other hand, frequency denotes the rate at which the motion repeats itself, indicating how often an event occurs within a specified period of time.
In this article, we will learn the differences between amplitude and frequency in detail.
