Refraction in a Glass Block
Below is a diagram of a ray of light entering a glass block. It is refracted as it enters the block, and again as it leaves.
· Draw the path of the light ray as it passes through the glass block and out the other side.
· Show and label:
- the path of the ray through the block
- the normal lines for the ray entering and leaving the block
- the angle of incidence (for the ray entering the block)
- the angle of refraction (for the ray entering the block)
Glass is ______ optically dense than air. This means that light travels more slowly in ______than ______.
As the ray enters the glass block it bends ______the normal, so the angle of ______is greater than the angle of ______.
As the ray leaves the glass block it bends ______the normal, so the angle of ______is greater than the angle of ______.
refraction more air away from
glass towards incidence less
