## Homework Statement

Find the observed frequency ##\nu## in terms of proper frequency ##\nu_0##, speed ##v## and radial velocity component ##v_r## for a source moving at velocity ##\vec v## with respect to the observer.

Now consider an observer in frame S where the source is seen moving at speed ##\vec v## along x-axis and at ##y=y_0##. At ##t=0##, the source is seen to emit frequency in ##-\hat y## direction. Find energy detected by the observer in terms of ##E_0## and ##|v|##.

## Homework Equations

## The Attempt at a Solution

**Part(a)**Not sure how to approach this part. We've always done problems in standard configuration..

Part (b)Part (b)

[tex]\nu = \gamma \nu_0[/tex]

[tex]E = \gamma E_0 = \frac{E_0}{\sqrt{1 - \frac{v^2}{c^2}}} [/tex]

Is this too easy to be true?
