Question

A flute plays a note with a frequency of 266 Hz. What is the speed of sound if the wavelength is 1.3 m?

Answer 1

f = 266hz
wavelength(lamda) = 1.3m
frequency = speed of sound / lamda 266 = speed / 1.3
speed = 266 * 1.3
speed of sound = 345.8 m/s

Answer 2

Hello friend,

¶ Velocity of sound -
- It is the distance travelled per unit time by a sound wave as it propagates through an elastic medium.
- Standard convention is to take speed of sound 343 m/s at 20° C in air.

◆ Answer-
v = 345.8 m/s

◆ Explaination-
# Given-
λ = 1.3 m
υ = 266 Hz

# Solution-
Velocity of sound is -
v = υλ
v = 266 × 1.3
v = 345.8 m/s

Therefore, velocity of sound in given condition is approx 346 m/s.

Hope this helps...
