Behavior of Waves: Interactions & Interference

When I comb or brush my hair I use a mirror. Light from my hair is __________ off the mirror and into my eyes.

• refracted

• reflected

• diffracted

• absorbed

Refraction occurs when

• a ray of light is bent.

• a ray of light bounces off a mirror.

• a fraction of light escapes a dark hole.

___________ occurs when a wave encounters an object. The wave goes around the object.

• Reflection

• Refraction

• Diffraction
