Interactions Of Waves

Reflections occurs when a wave

• bends due to a change in speed

• hits a surface and bounces back

• passes through an opening

• bends around barrier

Refraction occurs when a wave

• bends due to a change in speed

• hits a surface and bounces back

• passes through an opening

• bends around a barrier

Interference in which waves combine to form a wave with a larger amplitude than either wave originally had is called

• destructive interference

• amplitude enhancement

• constructive interference

• resonance

Tags

NGSS.HS-PS4-5

Points of maximum amplitude on a standing wave are called

• crests

• incidence

• apexes

• antinodes

Tags

NGSS.HS-PS4-1

Destructive interference in a standing wave produces points with zero amplitude called

• crests

• incidence

• nodes

• apexes

Waves do not bend when entering a new medium at a(n) right angle.

• True

• False

A wave refracts because one side of the wave changes speed before the other side.

• True

• False

NGSS.MS-PS4-2

A wave rises and spreads out in diffraction.

• True

• False

When the crest of one wave overlaps the trough of another wave ________________________ can occur.

• constructive interference

• amplitude interference

• destructive interference

• resonance

A standing wave is an increase in the amplitude of the vibration that occurs when external vibrations match an object's natural frequency.

• True

• False
