So the given frequency here is frequency mu, so that is 8 .50 multiplying 10 raised power 2.
00:16
And we have given here that the frequency is in kilohertz.
00:23
So now this can further be written as since 1 kilohertz that is equals to 1 ,000 ,000 ,000 ,000, hertz so here i can write that 8 .50 multiplying 10 raised power to multiplying 10 to power 3 hertz and now also 1 hertz is equal to 1 second inverse so we can write new is equal to 8 .50 multiplying 10 rift power 5 second inverse.
01:14
So now we have to calculate wavelength here.
01:22
There is a relation between frequency and wavelength and that is since new is equal to c divided by lambda.
01:32
So we can also write that lambda is equal to c divided by new.
01:37
C is the speed of light.
01:39
So that will be 3 .0 multiplying 10 raise to power 8.
01:46
Meter second inverse divided by the frequency we have here is 8 .50 multiplying 10 raise to power 5 second inverse...
