Question

What is the frequency of the wave if the wave has 4000 cycles in 4.5 seconds?

Answer 1

`888.bar(8)~~889` cycles per second.

Explanation:

The frequency is given by the number of cycles per second.

Here, the wave has `4000` cycles per `4.5` seconds, so its frequency is

`"frequency"=(4000 \ "cycles")/(4.5 \ "seconds")=888.bar(8) \ "cycles per second"`

I've rounded the cycles per second to a whole number to make the answer more reasonable.

`888.bar(8)~~889`
