PHYSICS PAPER 2 Flashcards
What is the correlation between angle of incidence and reflection
theyre equal
what does reflection practical find out
whether diffuse/specular reflection occurs on different materials
and if angle of reflection=incidence
1st step of reflection practical
use ruler to draw straight line on piece of paper
2nd step of reflection practical
place object on top of paper so edges line up with line drawn
3rd step of reflection practical
shine light ray using raybox and using pencil trace reflected beam on paper
4th step of reflection practical
draw normal to straight line at point at point light hit object
5th step of reflection practical
measure angle of incidence/reflection using protractor
6th step of reflection practical
measure width of incident and reflected beams
last step of reflection practical
Repeat for a range of objects, made from different materials.
if reflected beam in reflec practical is wider
diffuse reflection has happened
