Question

sound wave travel with a speed of about 330m/s what is the wave length of sound whose is 550hertz

Answer 1

wavelength=speed/frequency. wavelength=330/550=0.6m ans

Answer 2

$\huge\star\sf\underline\pink{Solution:-}$

We have,

$\sf{ Speed\:of\:waves (v) = 330 \:m/s} \\ \\ \sf{ Frequency\:of\:waves (f) = 550\: m/s} \\ \\ \\ \sf\underline\red{To\:Find:} \\ \\ \\ \: \: \: \: \bullet\sf{ Wavelength {( \lambda)} = ?}$

Now,

$\sf\underline\red{Formula:-} \\ \\ \\ \huge\bullet\pink{\boxed{\sf{ v = f \times \lambda }}}$

So,

After Entering the values in the Formula to get the exact values,

$\longrightarrow\sf{ 330 = 550 \times \lambda } \\ \\ \\ \longrightarrow{\sf{ \lambda = \dfrac{ 330}{550} }} \\ \\ \\ \longrightarrow\sf{ \lambda = 0.6\: m}$

Thus,

The Wavelength of Sound waves is 0.6 metres.

Additional Information:

• The minimum distance in which a sound waves repeats itself is called its wavelength.

• The SI unit for measuring wavelength is metre (m).
