Which of the following is true about light?

Light travels in waves

Light doesn't move

Light travels only in sound

Light travels in bundles

Light travels in waves AND in bundles called "photons".

It's hard to imagine something that's a wave and also a bundle.

But it turns out that light behaves like both waves and bundles.

If you design an experiment to detect waves, then it responds to light.

And if you design an experiment to detect 'bundles' or particles, then

that one also responds to light.
