What causes light to bend when it passes from air to water?

• Light travels at different speeds in different materials.
• Light waves spread out as they pass through narrow openings.
• Light bounces off the surface of the water.
• Light is absorbed by the water.

How does the size of an opening affect the amount of diffraction?

• The size of the opening has no effect on diffraction.
• The smaller the opening, the less diffraction occurs.
• The larger the opening, the more diffraction occurs.
• The size of the opening only affects reflection, not diffraction.

What is an example of how refraction is used in everyday life?

• A magnifying glass.
• A diffraction grating.
• A microscope.
• A telescope.

What is the difference between refraction and diffraction?

What is the normal line, and how does it relate to refraction?

How is diffraction used in microscopes?

Think about a time you saw light bend. How did this relate to the concepts of refraction and diffraction explained in the text?

The text explains how light bends when it passes through different materials. How does this relate to your own experiences with light and different materials?
