Assume that when I was 30 years old, I invented a spaceship capable of traveling at 95% of the speed of light, and take off to survey a peculiar infrared star 10 light years from earth. My daughter is 2 years old when I leave earth. I calculate that I age 20 years on my mission. A. while traveling to the star at 95% of the speed of light, I measure the wavelength of its light at 450 nm. What is the actual wavelength of the star's light? B. I turn around and head back to earth at 95% of the speed of light. WHat is the wavelength I see and I move away from the star? C. From my daughter prespective, how old is she when I return?

The principle of relativity was recognised as both a mechanical and optical effect. Einstein believed that the principle should hold for both situations. One of his thought experimentds involves him sitting on a train travelling at the speed of light and looking at a mirror. He asked the question as to whether he would be able to see his own reflection. a) Outline one possible answer to Einstein's question and the problems involved in your answer in terms of the principle of relativity. b) What was Einstein's conclusion to this thought experiment?c) The theory of relativity discusses the physical consequences of a universal frame of reference. The special theory of relativity, published in 1905 by Albert Einstein, is concerned with problems involving inertial frame of reference. Its fundamental principles, however, caused discrepancies in measurements. Describe TWO apparent discrepancies caused by these fundamental principles.
Processes at the center of a nearby galaxy cause the emission of electromagnetic radiation at a frequency of 3.97×1013 Hz.Detectors on Earth measure the frequency of this radiation as 3.11×1013 Hz. How fast is the galaxy receding from Earth?
Imagine our solar system is moving in the Milky Way toward a group of three stars. Star A is a blue star that is slightly closer to us than the other two.

Consider a spiral galaxy that is moving directly away from Earth with a speed V = 3.040×105 m/s at its center, as shown in the figure. The galaxy is also rotating about its center, so that points in its spiral arms are moving with a speed v = 6.950×105 m/s relative to the center. A) If light with a frequency of 7.543×1014 Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving toward the Earth? (Measurements of this type are used to map out the speed of various regions in distant, rotating galaxies.) Express your answer using four significant figures. B) If light with a frequency of 7.543×1014 Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving away from Earth? Express your answer using four significant figures.
A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 576.6 nm had been shifted to green with a wavelength of 562.3 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits. answer in m/s
