6) For a wave that has wavelength 3.00 m and frequency 5.00 Hz:

a) Calculate the wave speed.

b) Calculate the period of the wave.

a) The wave speed is 15 m/s.

b) The period of the wave is 0.2 m/s.

Explanation:

a) The wave speed is measured by the product of wavelength of wave with the frequency of the wave. As frequency and wavelength are inversely proportional to each other, wave speed is directly proportional to frequency and wavelength.

As here the wavelength is given as 3 m and the frequency is given as 5 Hz, the wave speed = wavelength × Frequency =3×5 = 15 m/s.

So the wave speed is 15 m/s.

b) The period of wave is inversely proportional to the frequency of the wave.

So period = 1/frequency

As the frequency is 5 Hz, the period = 1/5=0.2 s.

So the period of the wave is 0.2 m/s.

i'm just gonna leave this comment here, so i can get a challange done-
