Question 1 Report
two sound waves have frequencies of 12Hz and 10Hz. Calculate their beats period
Answer Details
When two sound waves of different frequencies overlap, they interfere with each other to produce a resultant wave. If the frequencies of the two waves are close, a phenomenon called beats occurs, where the amplitude of the resultant wave varies periodically.
The period of beats is given by T = 1/(f1 - f2), where f1 and f2 are the frequencies of the two waves.
Using the formula, we can calculate the beats period for the given frequencies:
T = 1/(12 Hz - 10 Hz) = 1/2 Hz = 0.5 s
Therefore, the answer is 0.5s.
