Question

If the speed of sound is 340 m/s what is the wavelength of a note of frequency
340 Hz,

Answer 1

Answer:

hopes, it will help you..........

Answer 2

Given:

★ The speed of sound is 340 m/s .

★ Frequency = 340 Hz

To be Calculated:

What is the wavelength?

Formula used:

Velocity of a wave = Frequency × Wavelength

Solution:

Velocity of a wave = Frequency × Wavelength

✪ Putting the values of velocity and frequency

➠ 340 = 340 × wavelength

➠ Wavelength = 340/340

➠ wavelength = 1 m

Thus, the wavelength of a sound wave is 1 m.

Extra information:

✪ Wavelength: The minimum distance in which a sound wave repeats itself is called its wavelength.

⟼ S.I unit of measuring in metre(m) .

✪ Frequency: The number of waves produced in one second is called frequency.

⟼ S.I unit of frequency is Hertz (Hz) .

✪ Velocity: The distance travelled by a wave in one second is called velocity of the wave.

⟼ S.I unit of measuring the velocity of a wave is metres per second ( m/s) .
