What do we see when we look into a mirror?
What is the angle of reflection relative to the angle of incidence?

True or False: Concave lenses are used to correct hypermetropia.
Remember which defect needs which type of lens.
You have a beam of light striking a glass block at a 30-degree angle. What is the angle of reflection? Now, predict the behavior of light as it exits the block into air.
Use the laws of reflection to guide your solution.
Design a simple experiment using a concave lens to test its effect on light. Explain what you would expect to see.
Think about how concave lenses diverge light.
