Question

What happens to the relativistic Doppler effect when relative velocity is zero? Is this the expected result?

Step-by-Step Solution

Answer

The observed velocity is equal to the emitted velocity when the relative velocity is zero. 

Step 1: Define Special Relativity

The special theory of relativity, sometimes known as special relativity, is a physical theory that describes how space and time interact. Theoretically, this is known as STR theory.

Step 2: Explanation

When, the value \({\rm{v  =  0}}\).

Then,the\({{\rm{f}}_{{\rm{obs}}}}{\rm{   =  }}{{\rm{f}}_{{\rm{source}}}}\), and the relative velocity is zero, the observed velocity equals the emitted velocity, according to the Doppler effect.

Therefore,when the relative velocity is zero then it is observed that the velocity is equal to the emitted velocity.
