Homework Help Overview

The discussion revolves around the Doppler effect, specifically the Doppler equation and its implications when both the source and detector are moving in the same direction at the same speed. Participants are exploring the effects on the equation's sign and the concept of relative speed in this scenario.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning how the sign in the Doppler equation changes when both the source and detector move together at the same speed. There is also inquiry into the concept of relative speed in this context and whether it affects the Doppler effect.

Discussion Status

The discussion is ongoing, with various interpretations being explored. Some participants suggest that there may be no Doppler effect under the specified conditions, while others are seeking clarification on the implications of relative motion.

Contextual Notes

There appears to be a lack of resources or references available to the original poster regarding this specific scenario in their textbooks.

hi what will happen to the sign on doppler's general equation when both source and dectector are moving in the same direction at the same speed.? I didnt find this on my books.? Does anyone knows?

dopler equation

F' = f (V +/- Vd)
------------
(V +/- Vs)


?
 
Physics news on Phys.org
Does anybody know about this?
 
if both source and dectector are moving in the same direction at the same speed, is there a relative speed between them?

then, does it matter what the sign is?
 
yeah both of them are at same direction at same speed 160 km
 
There won't be any doppler effect when both the observer and source is moving at the same rate of speed.
