What happens during reflection?

• Waves bounce off an object

• Waves are absorbed

• Waves change direction

• Waves pass through an object

Why do we hear echoes?

• Because sound waves are reflected by hard, flat surfaces

• Because sound waves are absorbed

• Because of diffraction

• Because of refraction

What causes the change in direction of waves known as refraction?

• The waves being scattered

• The waves passing through a gap

• The waves being absorbed

• The waves changing speed due to different densities

What determines the color of an object?

• Which wavelengths of light it absorbs and which it reflects

• The object's density

• The object's temperature

• The speed of light waves passing through it

What is the effect of diffraction?

• Waves change direction

• Waves spread back out after passing through a gap

• Waves are absorbed by the object

• Waves bounce off the object

Why does the sky appear blue?

• Because of the refraction of light in the atmosphere

• Because of the reflection of oceans

• Because of the absorption of blue wavelengths by the atmosphere

• Because of the scattering of shorter blue wavelengths
