Question

52. A sound of wavelength 68 cm, travels 850 m. in 2.5 sec. Calculate the velocity
of sound and frequency of sound.
a) 34 m/s and 5 hertz
b) 340 m/s and 3 hertz
c) 340 m/s and 5 hertz
d) 3.40 m/s and 50 hertz​

Answer 1

Answer:

your answer is C) 340 m/s and 5 hertz

Answer 2

Answer:

C

Explanation:

Wavelength= 68cm

Distance=850m

Time=2.5 sec

1) Velocity=distance/ time taken=850/2.5=340 m/s

2)Frequency=Velocity/ Wavelength= 340/.68= 500Hz
