Mastering Physics Solutions Chapter 29 Relativity
Chapter 29 Relativity Q.2P
Albert is piloting his spaceship, heading east with a speed of 0.90c. Albert’s ship sends a light beam in the forward (east-ward) direction, which travels away from his ship at a speed c. Meanwhile, Isaac is piloting his ship in the westward direction, also at 0.90c, toward Albert’s ship. With what speed does Isaac see?
Solution:
According to second postulate of special theory of relativity, the speed of light in vacuum, , is same in all inertial frames of reference, independent of the motion of the source or the receiver. The speed of Albert’s light beam observed by Isaac is c
Chapter 29 Relativity Q.3CQ
How would velocities add if the speed of light were infinitely large? Justify your answer by considering Equation 29–4.
Solution:
