Question

The temperature in a room is 56°C. What would the velocity of a sound wave be at this temperature?

A. 265.2 Hz
B. 1856.2 Hz
C. 364.6 Hz
D. 459.2 Hz

Answer 1

Answer:

C

Explanation:

The units of velocity are m/s, not Hz.  Make sure you wrote it correctly.

The speed of sound in air at sea level is approximately:

v ≈ 331.4 + 0.6 T

where v is velocity in m/s and T is the temperature in Celsius.

At 56°C:

v ≈ 331.4 + 0.6 (56)

v ≈ 365 m/s

The closest is C.

Answer 2

The velocity of the sound wave at the room temperature of 56° C is

364.6 m/s.

To find the velocity of sound wave, the given temperature is 56° C.

Here, we have to find the velocity not the frequency. The unit is given as Hz but we have to find in m/s.

What is the velocity of a sound wave ?

Velocity:

           The velocity of an object can be defined as the rate of change in the object's position corresponding to a frame of reference and time.

                             $\overline{v}={\frac{\Delta x}{\Delta t}}\\\overline{v} = average velocity\\{\Delta x} = displacement\\{\Delta t} = change in time$

The speed of sound in air at sea level is approximately:

                             v ≈ 331.4 + 0.6 T

where,

      v - velocity in m/s

      T - temperature in Celsius.

Substituting, at 56°C:

      v ≈ 331.4 + 0.6 (56)

      v ≈ 365 m/s.

Thus, Option C is the correct answer.
