Question
If two whistles are blown simultaneously, with respective frequencies of 505 Hz and 501 Hz, evaluate the beat frequency that is heard.
Solution
The beat frequency is calculated by finding the difference between the two frequencies. In this case, the frequencies are 505 Hz and 501 Hz.
Step 1: Write down the two frequencies. Frequency 1 = 505 Hz Frequency 2 = 501 Hz
Step 2: Subtract the smaller frequency from the larger one. Beat Frequency = Frequency 1 - Frequency 2 Beat Frequency = 505 Hz - 501 Hz
Step 3: Calculate the difference. Beat Frequency = 4 Hz
So, the beat frequency that is heard when the two whistles are blown simultaneously is 4 Hz.
