A bat emits ultrasonic sound of frequency 1000 kHz in air. If the sound meets a water surface, what is the wavelength of (a) the reflected sound, (b) the transmitted sound ? Speed of sound in air is 340 `ms^(-1)`, and in water 1486 `ms^(-1)`.

Explanation

To solve the problem of finding the wavelength of the reflected and transmitted sound when a bat emits ultrasonic sound of frequency 1000 kHz in air and it meets a water surface, we can follow these steps:

### Step 1: Understand the Given Data
- Frequency of the sound emitted by the bat, \( f = 1000 \, \text{kHz} = 1 \times 10^6 \, \text{Hz} \)
- Speed of sound in air, \( v_{\text{air}} = 340 \, \text{m/s} \)
- Speed of sound in water, \( v_{\text{water}} = 1486 \, \text{m/s} \)

### Step 2: Calculate the Wavelength of the Reflected Sound
