Wave Energyh amplitude waves correspond to louder sounds, larger ocean waves, and stronger earthquakes. This energy is often distributed unevenly over the different wavelengths or frequencies of the waves, which is shown graphically through intensity spectra. For example, plucking a guitar creates sound waves

GRAIN

Mechanical Wavesn physical media and they propagate due to a combination of restoring forces that pull the medium back toward its equilibrium state, and inertial effects that cause moving things to keep on moving. Sound waves are pressure waves in the air. People can hear a wide range of sound frequencies, but ther

MENT

Electromagnetic Waves create magnetic fields. These facts were well known for a long time but only loosely connected until James Clerk Maxwell realized that these fields become tightly linked when they change over time. Further, he realized that they could propagate indefinitely as electromagnetic waves, thus explaining

Thermal Radiationotal radiation. For example, embers in a campfire range from a dark red for ones that relatively cool to a bright white for ones that are very hot. Most people are familiar with the fact that dark colored objects absorb more sunlight than light colored ones, and hence heat up faster. This trend also
