Question

sound waves with a frequency of 2.5k Hz travels through a substance at speed of 650 m/s. calculate the wavelength of waves. ​​

Answer 1

Correct Question

• Sound waves with a frequency of 2.5Hz travels through a substance at speed of 650 m/s. calculate the wavelength of waves.

Given:

• Frequency (f) = 2
• Velocity (v) = 650 m/s

To Find:

• Wavelength of waves?

Solution:

$\\ \bigstar{\underline{\boxed{\sf{ Velocity_{(v)} = \blue{ Frequency_{(f)} \times Wavelength_{( \lambda )} } }}}}$

Let Suppose the Wavelength of wave be x.

$\\ {\underbrace{\sf\large\purple{ According \ to \ Question \: \: :}}}$

$\implies$ 650 = 2.5 × wavelength

$\implies$ 650/2.5 = wavelength

$\implies$ Wavelength = 260m

Hence,

• The wavelength of the wave is 260 m.
