Week 3 Doppler Effect & Lorentz Transformations

Question 1

what is the doppler effect equation for light

Answer 1

1/f = sqrt[ (1 + v/c) / (1 -v/c) ] x 1/f’

Question 2

what are Lorentz Transformations

Answer 2

equations that transform the coordinates of an event in one inertial frame into another and work under the assumptions of relativity

Question 3

give the 6 Lorentz Transformation equations (assuming motion in only the x axis)

Answer 3

1 x' = γ(x - vt)
2 t' = γ(t - vx/c^2)
3 y = y'
4 z' = z
5 x = γ(x' + vt)
6 t = γ(t' + vx'/c^2)
