Light

Question 1

What is the relationship between angle of incidence and angle of reflection?

Answer 1

They are equal

Question 2

Set up

Answer 2

Draw a straight line in the middle of a piece of paper with a ruler and draw a normal perpendicular to that in the centre
Place one edge of the block on the long line and draw around it
Plug in the ray box and set it up to make the smallest ray possible (turn it off when not using)

Question 3

Method

Answer 3

Draw along the ray until it reaches the normal
Draw along the middle of the reflected line
Draw along the middle of the line exiting the object
Work out the angle of the incidence ray and reflected ray
Connect the normal to the emergent ray and measure the angle it makes
