Wave Behaviors Lesson

When a wave strikes an object and bounces back that is

• Reflection

• Refraction

• Diffraction

• Interference

Constructive interference

• When the crest and trough overlaps, and meet each other

• When both crest of two different waves meet and they create a new wave

• When waves cross and cancel each other out

• When waves cross

The bending of a wave caused by the change in its speed

• Reflection

• Refraction

• Diffraction

• Interference

When the incident beam hits the mirror, the light reflects and bounces off the mirror, and the point where these two meets which is the angle of incidence. This process is called the

• Law of Light

• 3 steps of a mirror

• Law of Reflection

• Rarefraction

When an object causes a wave to change direction and bend around it

• Reflection

• Refraction

• Diffraction

• Interference

If the object is smaller than the wavelength the wave diffracts around it. If the object is larger than the wavelength the wave does not diffract around it very much.

• True

• False

When two or more waves overlap to form a new wave.

• Reflection

• Refraction

• Diffraction

• Interference

Three biggest things to remember about transverse waves

• perpendicular, goes to the right, side to side

• perpendicular, goes to any way, side to side

• perpendicular, goes to the right, goes up and down

• parallel, goes to the right, side to side

Frequency is measured in

• seconds

• minute

• hertz

• hours
