- @A student draws a ray of light as it passes through a block of glass. They drew Ray Z incorrectly because:
- #ref5
- It should be bent away from the normal when it leaves the block
- The ray is totally internally reflected, and so does not leave the block at the drawn point
- The ray must be drawn perfectly straight as it leaves the block as light always travels in straight lines
