Reflection and refraction are really interesting things that change how waves act. Let’s break it down!

Reflection:

• This happens when waves hit a barrier, which means they bounce off it.
• For example, when light hits a mirror, it reflects back to us.
• Also, sound waves can hit a wall and bounce back, making an echo.

Refraction:

• This occurs when waves move from one substance to another.
• A good example is when light travels from air to water.
• This change makes the waves bend. That’s why a straw looks bent when it’s in a glass of water.

Both reflection and refraction show us just how amazing waves can be!
