The special theory of relativity has what effect on measurements done today? (a) None whatsoever, because any correction would be negligible. (b) We need to consider the effects of relativity when objects move close to the speed of light. (c) We should always make a correction for relativity because Newton’s laws are basically wrong. (d) It doesn’t matter, because we can’t make measurements where relativity would matter.
A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s).
1. 4 light-seconds
2. 3 light-minutes
3. 2 light-days
4. 2 light-days, but this time answer in miles (enter just the number with no units)
The great proof of Einstein's Theory of General Relativity was that light is bent by gravity (as it travels through a curved
spacetime). Which of these statements is true??
O A light ray is bent the same amount, it doesn't matter how strong the gravity is.
O A light ray is bent less by an intense gravitational field.
O A light ray is bent more by an intense gravitational field.
O Light rays aren't bent.
