Asked by Oscar

Fig.1. Shows a signwave on the its horizontal axis "Time in (ms)" means that time is measured in milliseconds. The time taken is 20 ms in total

Question asks for frequency of the sinewave ?

Cant really draw Fig.. here :-0(

But the period is 5 milliseconds, the wave is repeated 4 times in time (20ms)

So f = 1 / .005 seconds so, f = 200 hz

Can some one check that is rgigt please ???

Thank you enjoy your day !
