In space, a stationary light source emits green light at a frequency of 5.50*10^14hz. a spaceship approaches the light at a speed 1.50*10^17m/s. what is the frequency of the light that is perceived aboard the spaceship. (the speed of light is 3.00*10^8m/s) a.6.08*10^14hz b.4.98*10^14hz c.5.50*10^14hz d.6.77*10^14hz

The problem has no physical meaning, since the spaceship cannot move faster than light

Explanation:

According to Einstein's special theory of relativity, nothing can travel faster than the speed of light in vacuum, whose value is

However, we see that in this problem, the spaceship is supposed to travel at a speed of

which is much larger than the value of c. This is not possible according to Einstein's theory of relativity: therefore, this problem has no physical meaning (and cannot be solved using the laws of physics as we know them, since they would violate the special relativity)

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
