energy can be considered as either a wave or particle 


Term

Definition
This is how it is diagramed 


Term
What is wavelength measured in?

Definition
C= speed of light
186,000 miles per second 


Term
Formula for relationship between wavelength,frequency, and speed of light 

Definition
λv=c
Wavelength and frequencey have inverse relationship 


Term

Definition
This is thesmalles amount of energy that can be transported by an electromagnetic wave 


Term
Particle perspective formula 

Definition
E=hv
h= planks constant 6.63 x 10^{34 }joules per second 


Term
how many calories is 1 joule?


Definition


Term

Definition
E (energy) increases when v (frequency) increases and frequency increses when when λ(wavelength) decreases
This means shorter wavelengths have more energy 


Term

Term
What does atmospheric scattering do 

Definition
reduces energy reaching earths surface 


Term

Definition
flux of incident energy decreases with distance from the source
Ex: further you get from a campfire colder it gets double th distance 1/4 flux 


Term

Definition
Emits and absorbs energy 100% effeciency 


Term

Definition
shows emission of radiation at different wavelengths
more radiation emitted at shorter wave lengths 


Term

Definition
λ_{max}= 2898/T
T= temperature in kelvin
wavelength with the highest radiation flux from object 


Term

Definition
F=σε T^{4}
epsilon= emissivity
sigma=stefan constant 5.67 x10^{8} w m^{2 }k^{4}
T= temperature in kelvin
