Equation representing a traveling wave

Constructive Interference: when two waves interfere to produce a larger amplitude. This happens when the waves are in-phase.

The speed of sound

Intensity of sound (I)

The Doppler Effect

Conduction is the process in which heat energy is transferred by adjacent molecular collisions throughout a material medium. The medium itself does not move

Convection is the process by which heat is transferred by the actual mass motion of a Fluid ( free convection-forced convection)

Radiation is the process by which heat is transferred by electromagnetic waves.

The heat capacity of a body is the ratio of heat supplied to the corresponding rise in temperature of the body. Heat capacity = Q/T

The specific heat capacity of a material is the quantity of heat required to raise the temperature of a unit mass through one degree. c = Q / mΔT

Thermal stress

Thermal force

Linear Expansion

Area Expansion

Volume Expansion

Lower fixed point This is the temperature of pure melting ice, at a pressure of a standard atmosphere.

Upper fixed point This is the temperature of dry steam from water boiling at a pressure of one standard atmosphere.

Fundamental interval This is the distance between the fixed points. It is divided into a number of equal divisions. Each division is one degree.
