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 Juno spacecraft arrived at Jupiter on July 4, 2016. Assuming the distance between the Earth and Jupiter is approximately 6.30 × 1011 m, determine the time, in minutes, for a signal traveling at the speed of light to reach Earth from Juno.
Remember that photon (particle of light) has no mass, so according to energy- momentum relationship, E² = (mc²)² + (pc)², the photon energy (E) is related to its momentum (py) by E₁ = pyc. A particle of mass M initially at rest completely absorbs a photon, after which its mass is 1.02M. Hint a. What was the energy of the incoming photon? Give your answer in terms of M, c, and other numerical factors. Ex = b. What is the momentum that the resulting particle moves with? Give your answer in terms of M, c, and other numerical factors. Momentum of particle of mass 1.02M is
The American physical chemist Gilbert Newton Lewis(1875–1946) proposed a unit of time called the “jiffy.” Accordingto Lewis, 1 jiffy = the time it takes light to travel one centimeter.(a) If you perform a task in a jiffy, how much time has it taken inseconds? (b) How many jiffys are in one minute? (Use the fact thatthe speed of light is approximately 2.9979 * 108m>s.)

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.

Compute the wavelength of the radio waves from the following stations. (a) an AM station operating at a frequency of 780 kHzm(b) an FM station with a frequency of 96.9 MHzm
The Planck time is the unique interval of time that can be built out of G, c, and h. Some physicists think that time intervals shorter than the Planck time have no meaning. Using G = 6.7 x 10-11 kg-1 m3 s-2, c = 3 x 108 m s-1, and h = 6.6 x 10-34 kg m2 s-1, calculate the Planck time, in units of 10-43 s.
