Module 39: The Relativistic Doppler Effect - Problem 2
I derived the Relativistic Doppler Shift formula for light waves, and noted that the same formula has to apply to rates associated with a series of light flashes. Here, you’ll work that out explicitly. To that end, imagine that George is firing photons toward Gracie at a rate of $N$ photons per second. Imagine that Gracie is running toward George at a speed $v$.
