A tuning fork of frequency 300Hzresonates with an air column closed at one end at `27^(@)`C. How many beats will be heard in the vibrations of the fork and the air column at `0^(@)`? End correction is negligible.

Explanation

To solve the problem step by step, we will follow these steps:

### Step 1: Understand the problem
We have a tuning fork vibrating at a frequency of 300 Hz and an air column closed at one end that resonates with this tuning fork at a temperature of 27°C. We need to find out how many beats will be heard when the temperature drops to 0°C.

### Step 2: Determine the speed of sound at different temperatures
The speed of sound in air varies with temperature. The formula for the speed of sound in air is given by:
\[
