Wave Intensity
Energy per time divided by surface area, measured in watts per meter squared.Power
The rate at which energy is transferred or converted, measured in watts.Surface Area
The total area over which a wave's energy is spread, affecting intensity.Three-dimensional Waves
Waves that radiate energy in all directions, like sound waves from a loudspeaker.Sphere
A three-dimensional shape used to model the surface area of wavefronts.Inverse Square Law
A principle stating intensity decreases with the square of the distance from the source.Distance
The measure of space between the wave source and a point where intensity is calculated.Watts per Meter Squared
The unit of measurement for wave intensity, indicating power spread over an area.Energy
The capacity to do work, carried by waves from one point to another.Loudspeaker
A device that emits sound waves, often used in examples of wave intensity.Siren
A sound source used to illustrate changes in wave intensity over distance.R1
The initial distance from a wave source used in intensity calculations.R2
The subsequent distance from a wave source where intensity is recalculated.I1
The initial intensity of a wave at distance R1.I2
The intensity of a wave at a new distance R2, used in inverse square law calculations.
