Wave Interactions
Chapter 10.3
Assignment #36
Reflection
• REFLECTION
• What happens when
a wave bounces back
after hitting a barrier
Sound Reflections
• Echo
• A reflected sound
wave
Refraction
• REFRACTION
• The bending of a
wave as it passes
from one medium to
another at an angle
Refraction of light in water
Refracted light
• PRISM
• When light passes
through a prism, the
light is refracted by
different amounts
– Light is spread out into
its separate colors
Diffraction
• DIFFRACTION
• Bending of waves
around a barrier or
through an opening
Interference
• INTERFERENCE
• Result of two or more
waves overlapping
Constructive vs. Destructive
Interference
• Constructive interference
• Crest of one wave
overlaps with the crest of
another wave
– Resulting wave has larger
amplitude
• Destructive interference
• Crest of one wave
overlaps with the trough
of another wave
– Resulting wave has smaller
amplitude
