Question

Calculate the speed sound for a frequency of 520 Hz and a wavelength 220 cm.

• A. 1144 m/s
• B. 1144 cm/s
• C. 1414 m/s
• D. 1441 m/s

Answer 1

The correct option is A

1144 m/s

Given: f = 520 Hz, λ = 220 cm = 2.2 m

Since, v = f $\times$ λ = 520 $\times$ 2.2

i.e. v = 1144 m/s (Answer)
