Beats are caused by the interaction of two waves with different periods. The Waves crests do not line up every oscillation, but when they do, they have a much larger than normal crest, which results in an observable beat.

How can one determine the beat frequency in a given system?

To determine the beat frequency in a given system, you can calculate it by finding the difference between the frequencies of the two interacting waves. The beat frequency is the frequency at which the amplitude of the resulting wave oscillates.

Two notes are sounding one of which is 370 Hz If a beat frequency of 5 Hz is heard what is the other note's frequency?

The other note's frequency would be either 365 Hz or 375 Hz. Since the beat frequency is the difference in frequencies between the two notes, you can either subtract or add the beat frequency to the known frequency to determine the other note's frequency.


How do you calculate the beat frequency?

The beat frequency is calculated by subtracting the frequencies of two sound waves. It represents the rate at which the amplitude of the resulting wave fluctuates.


What would the beat frequency be if you added tones of 880 Hz and 882 Hz?

The number of beats that we hear per second is the beat frequency. It is equal to the difference in the frequencies of the two notes. In this case: Beat frequency = 882 Hz - 880 Hz = 2 Hz. This means that we will hear the sound getting louder and softer 2 times per second.


What causes a frequency in a population to change after each generation?

Gene mutation causes the phenotype frequency in a population to change after each generation.


Two whistles produce sounds of wavelength 3.4 m and 3.3 m. What is the beat frequency produced?

The beat frequency is the difference between the frequencies of the two whistles. Here, the beat frequency would be 1 / (3.4 m) - 1 / (3.3 m) = 1 Hz.


What causes sideband frequency?

If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.
