Therefore the speed of the wave is 350000000 ms. The speed of a wave depends on the characteristics of the medium. The frequency f of a wave is the number of times a waves crests pass a point in a secondIf you watch a water wave in the bath pass over one of your toes twice every second the frequency of the wave is 2 Hz.
The unit Hz is short for hertz named after the German physicist Heinrich Hertz 1857 94.
The derived unit of frequency is hertz Hz. Lambda 2text m l 2m. What is the speed of an electromagnetic wave whose length is 35m and has a frequency of 100000000 Hz. Speed of light is the speed at which light waves propagate through different mediums.
