Question

5.) Two tuning forks resonate with air columns of length 16 cm and 20 cm, respective
If the lower frequency is 384 Hz, find the frequency of the other fork.
[Ignore the end correction.]​

Answer 1

480 Hz will be the frequency of the other fork

Explanation:

We are given:

• Length of lower side = 20 cm
• Length of upper side = 16 cm
• Frequency of lower side = 384 Hz

Solution:

Using the formula

XCf = XLf

20 x 384 = 16 x f

f = 20 x 384 / 16

f = 7680 / 16

f =480  Hz

Hence 480 Hz will be the frequency of the other fork.
