A mirror is a hard surface that reflects light. Reflections in a mirror are the object in the mirror is fliped around.
The scientist Isaac Newton, Robert Hooke and Albert Einstein all studied science. Light is matter or particals. Light travels in a staight line. But it can also bend. When light goes in a prism it separates into the colors of the rainbow. Red has the longest wavelength and violet has the shortest. Scientist still haven't decided what light is.
I learnt that a concave mirror makes the object that is in the mirror biger.
Here are photos of the scientist:
This is Robert Hooke.
