Wave Behavior and Vocab Quiz

What is the definition reflection?

• The bending of waves as they enter a new medium

• Bouncing back of waves from a surface that it can’t pass through

• The bending of waves as they pass through openings or around corners

• When two interfering waves have a displacement in the same direction, two crests and two troughs overlap. Increased amplitude.

What is the definition of Refraction?

• The bending of waves as they enter a new medium

• When two interfering waves have a displacement in the opposite direction, crest and trough overlap. Zero amplitude.

• When two interfering waves have a displacement in the same direction, two crests and two troughs overlap. Increased amplitude.

Light waves and sound waves are similar in that...

• They are both longitudinal waves

• They are both transverse waves

• They both transmit energy

• They both can travel through space.

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

• Reflection
• Refraction
• Absorption
• Transmission
