Question

1. A wave with a frequency of 14 Hz has a wavelength of 3 meters. At what speed will this

wave travel?​

Answer 1

Answer: 42m/s

Explanation:

The velocity of wave (v) depends on its frequency (f) and wavelength (x) by

v=x×f

Here, f=14Hz and x=3m

so, v=14×3

v=42m/s

Answer 2

Step 1: Given data

frequency of the wave, $\nu =14Hz$

Wavelength of the wave, $\lambda=3m$

speed of the wave, $s=?$

Step 2: Calculating the speed of wave

We know that,

$speed=frequency\times wavelength$

Thus,

$s=14\times 3=42m/s$

Hence, the speed of the wave is $42m/s$.
