What is the speed of a wave with a frequency of 0.2 hz and a wavelength of 100 meters?

The velocity of the wave is 20m/s

Explanation: The velocity of a wave can be obtained by the equation:

Velocity = wavelenght*frequency.

or v = λ*f

In this case, we know that: λ = 100 meters, f = 0.2Hz (where Hz means 1/s)

then, we have that the velocity of the wave is:

v = 100m*(0.2*1/s) = (100*0.2)m/s = 20m/s

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
