Answer to Problem 52A

  3×106m/s

Explanation of Solution

Given:

The actual frequency of the light, f=486nm

The observed frequency of the light, fobs=491nm

Formula used:

Doppler effect: The observed frequency of light can be written in terms of actual frequency of light (f) and the relative velocity of the source with respect to the observer (v) as,

  fobs=f(1±vc)

Where c is the speed of light.

Now, if the observer and the source are approaching each other, then the observed frequency is,

  fobs=f(1+vc)

And, if the observer and the source are receding away from each other, then the observed frequency is,

  fobs=f(1vc)

Calculation:

The speed of light is known as, c=3×108m/s

Thus for the given case, using the given values in above formula,

  fobs=f(1+vc)491×109=486×109(1+v3.0×108)1v3.0×108=1.01v=3×106m/s

Negative sign of above velocity denotes that the observer is moving away from the source, that is, the galaxy is moving away from the Earth.

Conclusion:

Hence, the relative velocity of galaxy with respect to the Earth is 3×106m/s .
