Question

if the frequency of a sound wave is 250 Hz and wavelenth is 1.32 m,then what is the velocity of the wave​

Answer 1

Answer:-

$\red{\bigstar}$ Velocity of sound wave $\large\leadsto\boxed{\tt\purple{330 \: m/s}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Given:-

• Frequency of sound wave = 250 Hz

• Wavelength = 1.32 m

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• To Find:-

• Velocity of the wave.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Solution:-

We know,

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{v = f \times \lambda}}}$

where,

• v = velocity of the wave

• f = frequency of the wave

• λ = wavelength

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting in the Formula:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf v = 250 \times 1.32$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ $\large{\bf\pink{330 \: m/s}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the velocity of the wave is 330 m/s.

Answer 2

Answer :-

• Velocity of the wave $\leadsto$ $\boxed{\tt{\red{330\:m/s}}}$

Given :-

• Frequency (f) = 250 Hz

• Wave length ($\lambda$) = 1.32 m

To find :-

• Velocity of the wave

Formula used :-

• $\boxed{\sf{\purple{v = f \times \lambda}}}$

Solution :-

$\sf{➪\:v = f \times \lambda}$

$\sf{➪\:v = 250 \times 1.32}$

$\sf{➪\:v =}$$\bold{\red{330\:m/s}}$
