Energy and Waves Study Guide

Matter through which a wave travels

• amplitude
• diffraction
• frequency
• medium

The greatest positive amplitude point on a wave

• trough
• crest
• pitch
• amplitude

The measurement from a point on one wave to the same point on the next wave 

• crest
• trough
• amplitude
• wavelength

The bending of waves as they pass from one medium to another (caused by a change in wave speed)

• compression
• rarefaction
• refraction
• diffraction

A wave in which energy travels parallel to the disturbance

• longitudinal
• transverse
• pressure
• electromagnetic

Any wave requiring a medium in order to transfer energy

• longitudinal
• transverse
• mechanical
• electromagnetc

The transfer of heat through rays (can transfer through a vacuum)

• conduction
• radiation
• convection
• refraction

The distance from the line of rest to the crest or trough on a wave (related to strength of wave)

• crest
• trough
• amplitude
• wavelength

The greatest negative amplitude point on a wave

• crest
• trough
• amplitude
• wavelength

Energy cannot be created or destroyed; it just changes forms

• Law of Energy Transformations
• Law of Conservation of Energy
• Law of Conservation of Matter
• Law of Gravitational Potential Energy
