Final answer:
In physics, beats are created when two waves with slightly different frequencies interfere with each other, resulting in a pulsating pattern. They are commonly used in music to tune instruments.
Step-by-step explanation:
In physics, the waves that have slightly different frequencies are called beats. Beats occur when two waves of slightly different frequencies interfere with each other. The interference produces a pattern of alternating constructive and destructive interference, resulting in a beat frequency.
For example, if you have two tuning forks, one with a frequency of 440 Hz and the other with a frequency of 442 Hz, when they are struck together, you will hear a pulsating sound due to the beats produced by the interference of these two frequencies.
Beats are commonly used in music to tune instruments. By producing beats with a reference tone, musicians can adjust the frequency of their instruments to match the desired pitch.
