    Hi everyone

    I've got the experiment for my physics 3 coursework and it's to do with refraction and i'm quite confused on the topic.

    If you're measuring the angle of incidence of the air to the perspex and then measuring the angle of refraction- should this angle be bigger or smaller due to the increased density of the Perspex box compared to the air??-----> hope this makes sense

    And also why does when shining the light from the ray box at the Perspex box at 90degrees then why does the light continue straight instead of refracting??

    Thanks and I appreciate all the help that anyone can give xxx
