In space, a stationary light source emits green light at a frequency of 5.50*10^14Hz. A spaceship approaches the light at a spee
d 1.50*10^7m/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
A spaceship approaches the light at a speed 1.50*10^7m/s which is about 5% of light speed. So the green light will shift towards the blue end of spectrum due to "blue shift."
The frequency should be higher which rules out option B and C. Looking at the magnitude of change, the correct answer should be A.6.08*10^14Hz,
There will be less green house gases released into the atmosphere, and this will decrease the rapid rate of climate change. And fracking fluid injected into the ground water reserves will decrease.
