Can anyone help with this Year 7 science homework?

[needanewnickname]

My son has some homework on the law of reflection. There is a diagram with lines on which asks him to "Draw the normal for each ray", then "Find the corresponding reflected ray and incident ray". Can anyone explain to me what this means or refer me to a good website to explain it? (NB It's not that I am doing my son's homework for him! He is unsure what he needs to do.)

Look at the bbc bitesize website. It must be on there. The angle of incidence = the angle of reflection. The normal is at right angles to the surface that the ray reflects from. He'll need a protractor. If the surface is not flat the ray will not come off at the same angle. I haven't explained it very well....check out the website! Good luck.

That's very helpful. Thank you.
