Facts of Electromagnetic Energy
1. form of energy that is given off by all matter
2. Radiate in form of transverse waves
Longer Wavelength= __________
Shorter Wavelenght= _________
Longer Wavelength=lower temperature, slower movement of particles
Shorter Wavelength= High temperature, more energy
Refracted Interactions
waves are bent as they pass through material sof varying density
Reflected Interactions
waves that bounced off a material
Scattered Interactions
waves in which energy is refracted and/or reflected in various directions
Transmitted Interactions
waves that passed through a material
Absobed Interactions
waves that are taken into a material
Heat Transfer
When energy transfer is between regions of high temperature to regions of lower temperatures.
Radiation
-uses transverse waves to carry energy and no medium is needed
-occurs through empty space but also travels through solids, liquids, and gases
Conduction
-transfer of heat energy from atom to atom or molecule when vibrating particles collide
-takes place through solids, gases, and liquids, not air
Convection
-transfer of heat by movement in fluids caused by density differences
Convection Cell
is where material with a higher density gets heated up and rises while the lower density materials is not changed by heat and gets a higher density falling to the bottom
Dynamic Equilibrium
a pint where there will be some transfer of energy, but the losses and gains are equal
Angle of insolation
angle of sunlight rays hitting the earth
Specific Heat
The amount of energy/heat needed to raise the temperature of that substance
smaller angle of insolation
dusk or dawn
transpiration
process by which plants release water vapor into the atmosphere
Reradiation
When stored heat energy from the ground radiated into the atmosphere in the form of infrared
Greenhouse Effect
method of heat retention and heating
At which temperature would an object radiate the least amound of electromagnetic energy?
Temp of North Pole
An object that is a good radiator of heat is also a good __________?
absorber
Which color is the best radiator of electromagnetic energy?
black
When is an object in radiative balance?
When the radiation emitted by the object is equal to that absorbed by the object
At which temperature would an object radiate the least amound of electromagnetic energy?
Temp of North Pole
An object that is a good radiator of heat is also a good __________?
absorber
Which color is the best radiator of electromagnetic energy?
black
When is an object in radiative balance?
When the radiation emitted by the object is equal to that absorbed by the object
