PS Module 9: Introduction to Waves

a measure of the size of the disturbance of a wave, related to the energy that it carries

• amplitude

• crest

• period

• wavelength

denser region of a longitudinal wave

• compression

• crest

• diffraction

• rarefaction

highest point on a transverse wave

• crest

• trough

• wavelength

• node

bending of waves around an obstacle; can also occur when waves pass through a narrow opening

• diffraction

• rarefaction

• refraction

• resonance

number of wavelengths that pass a fixed point each second

• frequency

• period

• wavelength

• amplitude

Tags

NGSS.HS-PS4-1

process of two or more waves overlapping and combining to form a new wave

• interference

• resonance

• standing wave

• mechanical wave

wave in which the matter in the medium moves back and forth along the direction that the wave travels

• longitudinal wave

• mechanical wave

• standing wave

• transverse wave

wave that can only travel through matter

• mechanical wave

• longitudinal wave

• standing wave

• transverse wave

matter through which a wave travels

• medium

• node

• wave

• trough
