      Really fast and in waves. It hard to know the best way to explain it without knowing how old you are, but bbc bite size has some good videos on how light travels.

      Great question!

      People were quite unsure for a while, because they couldn’t decide whether it travelled in particles (bits) or waves (wobbly lines).

      They now think that it’s a bit of both, with particles of light travelling as waves.

      I’m not a physicist, so that’s about as technical as I can get, but as Ali suggests, go check out some bbc vids on how light travels!
