waves that Can travel through vaccum
Electromagnetic waves
is an electromagnetic wave
Light
the length of one complete cycle of a wave
Wavelength
the number of cycles that Pass a Point per unit time
Frequency
the separation of light into different colors which appear in order according to frequency
Dispersion
is the result of a mixture of all the colors of light
White
is the absence of the wavelengths of the visible light spectrum
Black
Process of absorbing and reemitting light in all directions
Scattering
scattering Of light by Particles in a medium without Change in wavelength
Rayleigh scattering
the average Kinetic energy of the Particles of matter, can be measured by a thermal meter or a thermometer
Temperature
absolute temperature scale 0 K - absolute zero
Kelvin Scale
is the international system of unit used in scientific Work
Kelvin
the energy transferred from an object with higher temperature to an object with lower temperature, it is measured in Joules
Heat
having a low amount of thermal energy relative to the thermal energy of the environment or to another object
Coldness
having a high amount of thermal energy relative to the thermal energy of the environment or to another object
Hotness
the state when two or more objects that are in contact with each other reach a common temperature
Thermal Equilibrium
the amount of heat required to raise the temperature Of one gram of water by One degree Celsius
Calorie
a device used to measure the amount of heat transferred to or from an Object
Calorimeter
the tendency of matter to change its size in response to a change in temperature
Thermal expansion
is the quantity of heat necessary to raise the temperature of a substance by 1°C
Heat capacity
the amount of heat required by a unit mass to raise its temperature by one degree Celsius
Specific heat capacity
