| Term | Definition |
|---|---|
| Wave | A disturbance that moves through matter and space. |
| Transverse Wave | Causes particles in matter to move back and forth at right angles to the direction in which the wave travels. |
| Compressional Wave | Causes particles in matter to move back and forth along the same direction in which the wave travels. |
| WaveLength | The distance between one point on a wave and the nearest point moving with the same speed and direction. |
| Frequency | The number of wavelengths that pass by a point each second. |
| Law of Reflection | The angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with normal. |
| Refraction | The change in direction of a wave when it changes speed as it travels from one material to another. |
| Diffraction | The bending of wave around an object. |
| Nuclear Reactions | A change in the identity or characteristics of an atomic nucleus that results when it is bombarded with an energetic particle, as in fission, fusion, or radioactive decay. |
| Light Energy | Radiant energy is the energy of electromagnetic waves. |
| Sun`s Radiation | A solar radiation sensor measures solar energy from the sun. |
| Energy Transfer | Energy transfer is the transfer of energy from one object or material to another. |
| Vibration | An instance of vibrating. |
| Water Wave | Water waves are surface waves, a mixture of longitudinal and transverse waves. |
| Waves | A long body of water curling into an arched form and breaking on the shore. |
| Energy | The strength and vitality required for sustained physical or mental activity. |
| Seimic Wave | An elastic wave in the earth produced by an earthquake or other means. |
| Matter/ Medium | Physical substance in general. |
| Solid Wave | A wave that goes through solids. |
| Pitch | The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone. |
| Atmosphere | The envelope of gases surrounding the earth or another planet. |
| Troposphere | The lowest region of the atmosphere. |
| Stratosphere | The layer of the earth's atmosphere above the troposphere. |
| Mesosphere | The region of the earth's atmosphere above the stratosphere and below the thermosphere. |
| Ionosphere | The layer of the earth's atmosphere that lies above the mesosphere. |
| Thermosphere | The region of the atmosphere above the mesosphere. |
| Exosphere | The outermost region of a planet's atmosphere. |
| Air Mass | Large body of air with properties that resemble the part of earths surface over which it develops. |
| Front | Boundary between 2 air masses of different density, moisture, or temperature. |
| Tornado | Violently rotating column of air in contact with ground. |
| Hurricane | Large, swirling, low pressure system that forms over the warm Atlantic ocean. |
| Blizzard | A severe snowstorm with high winds and low visibility. |
| Cold Front | The boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system. |
| Warm Front | The boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system. |
| Occluded Front | A composite front produced by occlusion. |
| Stationary Front | A boundary between two different air masses, neither of which is strong enough to replace the other. |
