@Daniel.

Micro represents 10^-6.

Same doubt as Daniel. Please clarify our doubt.

Where from 10^-6 @Jaya and @Swapnil.

Given that t = 400 micro sec.

F = 1/t.

F = 1/400*10^-6 = 2500.

F = 1/T.

F = 1/400.

F = 2.5*10^3.

F = 2500.

f = 1/t = 1/400*10^-6 = 10000/4 = 2500 hz.

400micro sec
f=1/t
f=1/400*1000000
f=2500hz
