The Attempt at a Solution
When the source is not moving, ## \lambda = 6250 A ## ...(1)
When the source is moving, ## \lambda ' = 6500 A ## ...(2)
From (1) and (2),
## \lambda ' > \lambda ## ...(3)
This means that the source is moving away from the Earth.
## \nu ' = \nu \sqrt{ \frac { c+v}{c-v} ##
## {\frac { \lambda }{\lambda '} }^2 = { \frac { c+v}{c-v} ##
0.9245c –c = v(1+0.9245)
V =11760 km/s
Is this correct?
