Important Questions on Light

The diagram shows a device that uses mirrors to see around corners.
The device is used to look at a sign that says 'HOSPITAL'. Will the image seen by the observer at point X be swapped over or still be the correct way round? Explain your answer.

The diagram shows arrangements of two different substances, A and B, that are placed next to each other so they touch. The table shows the possible combinations of A and B. Choose which combinations will show refraction at the boundary between A and B. Choose the pairs given below which shows refraction.


The diagram shows the surface of a lake of water. A lamp has been placed on the bottom of the lake.
Add a normal line at point 'X'.

Describe how the direction light ray changes as it enters the air.

Look at the diagram of a glass block surrounded by air. The incident ray is shown.
Think about what happens at point X. Draw a normal at X and the path of the refracted ray inside the glass block.

Look at the diagram of a glass block surrounded by air. The incident ray is shown.
Add the label 'Y' where your first refracted glass ray leaves the glass block.
