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?
