Answer 2

The frequency is 0.25Hz and the speed of the wave is 0.4m/s.

What is frequency and speed of the wave?

Wave frequency is the number of waves that pass a fixed point in a given amount of time. This equation shows how the three factors are related: Speed = Wavelength x Wave Frequency.

To find the frequency and speed of the wave.

λ=1.6m,T=4s

f=1/T

f=1/4s

f=0.25Hz

The frequency of the wave is 0.25Hz

speed=fλ

speed=(0.25×1.6)m/s

speed=0.4m/s.

The speed of the wave is 0.4m/s.

The frequency is 0.25Hz and the speed of the wave is 0.4m/s.
