Homework Statement

Describe what happens to an object traveling close to the speed of light from
the point of view of a stationary observer.
(Hint--there are three differences).

The Attempt at a Solution

I just don't understand what it means by there being three differences?

It is asking what characteristics differ (and how they differ) from that of the same object viewed in the observer's own frame ( or in a frame moving at non-relativistic speeds relative to the observer).

Unless one is talking about such things as colour, I can only think of two things that are different.
