Hmmm......this week we've done so many things and its like having fun!! We are enjoying at the same time we are learning .I learned about the history of light...the corpuscular theory and the wave theory...both theories are accepted toady but we don't know when will it last. Also, we discussed about refraction and reflection....The angle of reflection and the angle of incidence. The angle of reflection is made by reflected ray and the normal (angles with a line perpendicular to the surface) while the angle of incidence is made by the incident ray and the normal(angles with a line perpendicular to the surface), therefore the angle of incidence is equal to the angle of reflection.
