How fast do different parts of the EM spectrum travel in a vacuum?

Answer 1

At the speed of light.

Remember that the EM spectrum are comprised of energy waves. Light is an energy and is part of the EM spectrum.

Speed of light in a vacuum is #299 792 458 m/s#. Most people round to #3.0xx10^8#. However the speed alters when travelling in through a medium, like water or air.

Hope this helps :)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
