ulagram of a voltage dividerAssume that when I was 30 years old, I invented a spaceship capable of traveling at 95 %che speed of light, and take off to survey a peculiar infrared star 10 light years from earthMy daughter is 2 years old when I leave earth. I calculate that I age 20 years on my missionWhile traveling to the star at 95 % of the speed of light, I measure the wavelength of1light at 450 nm. What is the actual wavelength of the star's light?I turn around and head back to earth at 95 % of the speed of light. What is the wavelengI see as I move away from the star?rom my daughter's perspective, how old is she when I return?
