Consider a blob of luminous matter moving along a direction [tex]\hat{x}[/tex] at an angle [tex]\theta[/tex] to your line of sight at a relativistic speedv.

(a) According to you, the stationary observer at a distanced, what is the apparent transverse velocity of the blob? Hint: you must take into account light travel time effects.

(b) If the blob emits light monochromatically at frequency [tex]\omega_0[/tex] in its rest frame, what frequency will you measure in the lab frame?

2. Relevant equations

3. The attempt at a solution

The main difficulty I'm having is dealing with the blob moving off axis from the line of sight of the observer (also, I'm a bit confused on the wording of the problem). I know the traditional relativistic motion and frequency effects, but they assume motion directly on axis with the observer. Anyone have some insights to help me in solving this?
