Waves

The speed of sound in air is affected by temperature. At 0°C, the speed is 331 m/s. The relationship between the speed of sound in air and temperature can be expressed by the formula:

v = v₀ + 0.6 \times T

where:

• v is the speed of sound at temperature T (in °C),
• v₀ is the speed of sound at 0°C,
• T is the temperature in degrees Celsius.

Given that v₀ = 331 m/s and T = 35°C, substitute the values into the formula:

v = 331 + 0.6 \times 35

Calculate the result:

• 0.6 \times 35 = 21

Add this to the initial speed at 0°C:

v = 331 + 21 = 352 m/s

Therefore, the speed of sound in air at 35°C is approximately 351.6 m/s.
