Question 1
Given an observer at rest measures light traveling 300,000 km, how would this distance change if measured from an object moving at half the speed of light?
💡 Hint: Use the speed of light in calculations.
Question 2
A spaceship travels at 0.9c. How would you calculate the proper time for an observer on Earth versus an astronaut aboard?
💡 Hint: Proper time is what the astronaut will measure.
