A bat flies perpendicularly towards a wall with a speed of 6 m/s, emitting sound of frequency 450 kHz. What is the frequency of the wave reflected from the wall that it will hear? Given `c=340m//s`?

Explanation

To solve the problem, we will use the Doppler effect formula to find the frequency of the sound wave reflected from the wall that the bat will hear.

### Step-by-Step Solution:

1. **Identify the given values:**
- Speed of sound, \( c = 340 \, \text{m/s} \)
- Speed of the bat (observer), \( V_o = 6 \, \text{m/s} \)
- Frequency of sound emitted by the bat, \( \nu = 450 \, \text{kHz} = 450 \times 10^3 \, \text{Hz} \)
