Answer:
v-rel = 16.8
Make sure to read the explaination so you can solve it yourself!
Explanation:
I had this same question on Acellus, here is how I answered it:
Equation being used: Δf = 2*fο*vrel/c
( this equation can be found in the bottom of the lesson manual in the help tab)
Where,
Δf = change in frequency; 672
fο = frequency before being doppler shifted; 6.00 * 10^9
vrel = relative velocity; unknown
c = speed of light; 3.00 * 10^8
Now that we have written the numbers we know down, we must rearrange the equation for the velocity (vrel)
Starting Equation:
Δf = 2*fο*vrel/c
Multiply by c, then divide by 2fo to isolate vrel.
This will leave us with the equation:
Δfc/2fo, now we plug in the numbers
(672 * (3*10^8)) / (2* (6.00*10^9))
Once we plug this into the calculator, you should get
16.8
I hope this helped you, Wawawewa!
