Question

Use F = 1/T as your basis:

10. A stroboscope is set to flash every 8.00×10−5s. What is the frequency of the flashes?

The answer is 12,500 Hz but please show your work.

Answer 1

• Time=T=8×10^-5s

Now

`\\ \rm\rightarrowtail \\u=(1)/(T)`

`\\ \rm\rightarrowtail \\u=(1)/(8* 10^(-5))`

`\\ \rm\rightarrowtail \\u=0.125(10^5)`

`\\ \rm\rightarrowtail \\u=12500s^(-1)`

`\\ \rm\rightarrowtail \\u=12500Hz`
