Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question about a problem on superluminal motion. Using the following figure (see attachment) I have to derive that:

a) [tex]\beta[/tex] = [tex]\frac{v}{c}[/tex] = [tex]\frac{1}{cos(\theta)+sin(\theta)}[/tex]

b) Plot [tex]\beta[/tex] as a function of [tex]\theta[/tex] and show where the superluminal motion takes place

Thanks!
