Explanation:
Acc. to Einstien's postulate of special theory of
Relativity ,
Velocity of the light beam is same in all frames of references
(a) If the freight car is at rest
The frame we can assumed as Non - inertial frame of reference
s
In the inertial frame of reference , velocity of the light beam has its own value as : 3 x 10^8 m/s
(b) If the freight car is moving , the frame we can assumed as Non -inertial frame of reference
In thus case also , The velocity of the light beam will also have the same value as ; 3 x 108 m/s
Answer:
The period is ![T = 0.00255 \ s](https://tex.z-dn.net/?f=T%20%20%3D%20%200.00255%20%5C%20%20s)
Explanation:
From the question we are told that
The frequency is ![f = 392 \ Hz](https://tex.z-dn.net/?f=f%20%20%3D%20%20392%20%5C%20Hz)
Generally the period is mathematically represented as
![T = \frac{1}{f}](https://tex.z-dn.net/?f=T%20%20%3D%20%5Cfrac%7B1%7D%7Bf%7D)
=> ![T = \frac{1}{ 392}](https://tex.z-dn.net/?f=T%20%20%3D%20%5Cfrac%7B1%7D%7B%20392%7D)
=> ![T = 0.00255 \ s](https://tex.z-dn.net/?f=T%20%20%3D%20%200.00255%20%5C%20%20s)
