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 !
correct. f=1/T
Thank you Bob
if boston is 14 feet above sea level and the ice cap is 680,000 cubic miles of water what impact would boston have?
To find the frequency of a sine wave, you need to know the period of the wave, which is the time taken for one complete cycle. In this case, the period is given as 5 milliseconds.
Frequency (f) is the reciprocal of the period (T), so you can calculate it using the formula:
f = 1 / T
Substituting the given value for the period, we get:
f = 1 / 0.005 seconds
To convert milliseconds to seconds, you divide by 1000, so:
f = 1 / 0.005 seconds = 1 / 0.005 milliseconds/1000 = 1 / 0.000005 seconds
Simplifying further:
f = 200,000 hertz (Hz)
So the frequency of the sine wave is 200,000 Hz.
