Question

A sound wave in a steel rail has a frequency of 620 Hz and a wavelength of 10.5 m. What is the speed of
sound in steel?

Answer 1

Answer:

620 / 10.5 =.

solve it u can get your answer

Answer 2

Answer:

As, ʋ=vλ

Here, v=620Hz, & λ=10.5m

∴ speed(ʋ)=620×10.5

Therefore, the speed of sound in steel is accordingly=6,510m/s
