A person travels on a spaceship moving at a speed of 5c/13.
(a) Find the time interval calculated by him between the consecutive birthday celebrations of his friend on the earth.
(b) Find the time interval calculated by the friend on the earth between the consecutive birthday celebrations of the traveler.
The speed of spaceship =5c/13
(a) consecutive birthday celebration means the time period t= 1 year.
But the time interval observed by the person is spacecraft will be
Thus, the time interval observed by the person will be more than one year i.e. 1.08 years (approx.)
(b) The person on Earth will also calculate the same time interval because for him also, the person in spacecraft is travelling with same speed.
