- What was the purpose of the Michelson-Morley Experiment?
b. To detect the presence of the luminiferous ether.
- What did the Michelson-Morley Experiment conclude?
. The speed of light is constant in all directions.
- Which instrument was used in the Michelson-Morley Experiment?
Interferometer
A rocket is traveling from earth through space at a speed of 2.7x10^8 ms-1. The
pilot measures the journey to take 240 minutes. How long does mission control on
Earth think the flight lasted for? (Hint: C = 3,000,000 m/s)
a) 550 min
Which of the following statements best describes time dilation?
c) Time slows down as an object approaches the speed of light.
Which of the following statements best explains why time dilation is not constant
for all observers, even though the speed of light in a vacuum is constant for all
observers?
Time dilation is a result of relative motion between observers.
