i. Sound wave is a longitudinal wave.
ii. Sound cannot travel in vacuum.
iii.
a. Reverberation is the phenomenon in which sound waves are reflected multiple times causing a single sound to be...
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...
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 \(\frac{λ_l}{λ_a}\) =...
