Waves Review

How is refraction different from reflection.

• Reflection is the bouncing of light off an object and refraction is the bending of light when it moves through one kind of matter to another.
• Reflections is the bending of light when it moves through one kind of matter to another and refraction is the bouncing of light off an object.

The bending of light as it passes at an angle from one medium to another is called ________________.

• lens
• absorption

Hey!  That straw looks broken.  Why?

• reflection
• refraction
• transmission
• absorption

When standing in the sun this behavior allows you to warm up as light and other waves hit your clothes.

Which two media does light waves travel the same in?

• Air and Water because it travels at 300,000,000 m/s through these media.

• Water and Perspex because it travels at 230,000,000 m/s through these media.

• Perspex and Glass because it travels at 230,000,000 m/s through the media.

• Glass and Diamond because it travels at 242,000,000 m/s through the media.

Light waves travels fastest through the air because air is a gas, which means it is less dense than the other media, which are solids and liquids.

• true

• false

Sound does not travel in space because

• Space is too far away.
• There is no matter in space.
• Space is the final frontier
• Space has planets.

Sound waves travel the fastest in

• solid

• liquid

• gas

• vacuum of empty space
