What is the result of combining all colors of the visible spectrum?

Answer 1

The simple answer is "white" light, but it depends...

"Why does red light plus green light give you yellow light?" is one of my favorite questions to stump people who know just a little bit about physics.

Since pure yellow light has a frequency that lies in the middle of red and green light, how is it possible for longer and shorter waves to combine to produce an intermediate wavelength?

They don't.

Pure red and pure green combined have an effect on our eyes that is comparable to that of pure yellow light.

In response to your question, the perceived color white is achieved when all of the visible spectrum's colors are mixed together in the proper ratios.

Bonus

Officially, the universe is beige.

Second Bonus

Magenta is not one of "all the colours of the rainbow".

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.
