A Helmholtz resonator is observed to oscillate at 400 Hz when someone blows across the top of it. If it is filled halfway up with water and then air is blown across it, what frequency would it resonate at?

Step 1

The formula for the frequency of Resonance is:

Step 2

The resonator is same only the volume of the cavity is changed. Therefore, the relation between the new frequency and original frequency is:

Step 3

Now, it is filled halfway with water. Theref...
