When you approach a blinking source of light, the frequency of its blinking is seen to: decrease, increase, or remain the same always.
I THINK IT IS INCREASING.
If you are traveling at close to the speed of light and shine a flashlight out in front of you, a third observer at relative rest will see the beam moving: slower than the speed of light, faster than the speed of light or at the speed of light
I THINK IT IS AT THE SPEED OF LIGHT.
Thanks for all the help! This chapter has me confused!
On the first: You still sense time the same. Your clock says it is the same. But in truth, your clock is slowing, however you cant know that until you slow down and compare your watch to a referece.
The second is ok.
