A sound note emitted from a certain source has a velocity of 300 m/s in air and 1050 m/s in water. If the wavelength of sound note in air is 2 m, the wavelength in water is …..
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 \(\frac{λ_l}{λ_a}\) =...
HCF of two numbers = 25
Product of two numbers = 1050
Let their LCM be x.
Using the formula, Product of two numbers = HCF × LCM
We conclude that,
1050 = 25 ×...
