Tuning Fork Frequency and Beats

The video tutorial explains a problem involving tuning forks A and B, focusing on frequency changes when filing one of the forks. The instructor uses the finger technique to demonstrate how the frequency of fork A increases when filed, affecting the beat gap. The tutorial concludes by determining the unknown frequency of fork B using the given data.

What technique is introduced to solve the problem of beats?

• Sound technique

• Wave technique

• Vibration technique

• Finger technique

What is the known frequency of tuning fork A?

• 300 Hz

• 350 Hz

• 250 Hz

• 200 Hz

What is the initial beat gap between the two tuning forks?

• 2 beats

• 5 beats

• 4 beats

• 3 beats

What happens to the frequency of tuning fork A when it is filed?

• It increases

• It remains the same

• It fluctuates

• It decreases

How does the beat gap change after filing tuning fork A?

• It decreases

• It remains the same

• It increases

• It disappears

What conclusion is drawn about the relationship between A and B after filing?

• A is greater than B

• A is equal to B

• A and B are unrelated

• A is smaller than B

What is the formula used to determine the frequency of B?

• n + NB = Delta n

• n - NB = Delta n

• n / NB = Delta n

• n * NB = Delta n

What is the value of Delta n used in the calculation?

• 3

• 5

• 2

• 4

What is the final calculated frequency of tuning fork B?

• 252 Hz

• 246 Hz

• 250 Hz

• 248 Hz

What is the purpose of the second beat gap information provided?

• To confuse the students

• To solve the problem

• To calculate the frequency of A

• To determine which fork is larger
