A bat emits ultrasonic sound of frequency 1000 kHz in air. If the sound meets a water surface, what is the wavelength
Given: n = 1000 kHz = 106 Hz, va = 340 m/s, vw = 1486 m/s To find: Reflected wavelength (λR), Transmitted wavelength (λT), Formula: v = nλ Calculation: In different medium, frequency of sound wave remains same. From formula, Sound is...

The wavelength of a sound note is 1 m in air and 2.5 m in a liquid. Find the speed of sound in the liquid, if the speed
Given: λa = 1 m, λl = 2.5 m, va = 330 m/s, To find: Speed of sound (vl) Formula: v = nλ Calculation: From formula, Since the frequency n remains the same, va = nλa and vl = nλl ∴ \(\frac{v_l}{v_a}=\frac{λ_l}{λ_a}\) ∴ vl = va \(\frac{λ_l}{λ_a}\) =...
