- Homework Statement:
- There is a spaceship moving in the +x direction gets a signal from a source on xy plane. From the reference frame of stable stars, the speed of the spaceship is v and the angle that signal creates between x axis and its direction when reached the spaceship is θ. Get help from lorentz transformations and find out the angle θ in the reference frame of spaceship.
- Relevant Equations:
I didn't use but maybe: t'=(t-(vx)/c^2)/sqrt(1-v^2/c^2)
That's what I found. But the answer is arctan(sinθ*sqrt(1-v^2/c^2)/(cosθ+v/c))
