A wave has a period of 2 seconds and a wavelength of 4 meters. Calculate its frequency and speed. Note: Recall that the frequency of a wave equals 1/period & the period of a wave equals 1/frequency.

Respuesta :

Answer:

frequency = 0.5 Hz and speed = 2 m/s

Explanation:

Given that,

The period of a wave, T = 2 s

Wavelength, [tex]\lambda=4\ m[/tex]

If f be the frequency. So,

f = 1/T

[tex]f=\dfrac{1}{2}\\\\f=0.5\ Hz[/tex]

Speed of a wave is given by :

[tex]v=f\lambda\\\\v=0.5\times 4\\\\v=2\ m/s[/tex]

So, the frequency of the wave is 0.5 Hz and speed is 2 m/s.
