Question

What is the wavelength of a wave with f = 0.9 Hz and v = 154.9 cm/s

Answer 1

168 cm.

Step-by-step explanation:

this is what I got. sorry if wrong

Answer 2

The wavelength of a wave is 1.72 m.

Step-by-step explanation:

Given,

Frequency, f = 0.9 Hz

Speed of a wave, v = 154.9 cm/s = 1.549 m/s

The speed of a wave is given by :

`v=f\lambda`

`\lambda=(v)/(f)\\\\\lambda=(1.549\ m/s)/(0.9\ Hz)\\\\\lambda=1.72\ m`

So, the wavelength of a wave is 1.72 m. Hence, this is the required solution.
