Observer A sees a flash of blue light at position x1 = 10.4m and at time t1 = 0.124µs, and a flash of yellow light at position x2 = 21.3m and at time t2 = 0.139µs. Observer B, who is in motion relative to Observer A, sees these flashes of light occur simultaneously. At what speed is Observer B traveling relative to Observer A?

Expert Solution

This is the problem related to Special theory of relativity.

Given

For Observer A:

Two events (seeing flash of blue and yellow light) are separated by the distance

Difference in time in the occurrence of two events

For Observer B:

Two events occur simultaneously.

Here let us consider that Observer B is moving with velocity with respect to Observer A.

We have the differential form of Lorentz transformation as

But

c is speed of light.

or

The speed at which Observer B traveling relative to Observer A is

1. Special Relativity (a) An observer sees a πon moving past with momentum ~p. In the rest frame of the πon, it decays into a µon and a νtrino in perpendicular directions to the direction in which the observer is moving. Find the velocity of the µon in the rest frame of the πon. (b) Find the velocity of the µon in the frame of the observer. What angle does it make with the direction of the πon's motion? Repeat...

blue light lenses You can write about a blue light lens The only criteria is that the write up must touch on 3 areas: What is the problem this product (or technique) can solve What are its limitations What are its competing products This is basically an essay about an optical product that you either are familiar with, or research. No calculations, no maths, and no more than 2 pages.
