What is Planck's Equation?
E=hv
100
What has no mass but has energy?
Photons
100
What happens to the number of electrons when there is a high intensity of light?
The more electrons are dislodged.
100
What happens to the released electrons when the frequency of the incoming light is greater?
The more electrons are released.
100
What is the speed of emitted electrons directly related to?
Their kinetic energy
200
What does each letter in Planck's Equation Represent
E=Energy h= Constant v- Frequency
200
What are photons a force carrier of?
The electromagnetic field.
200
What does a higher intensity actually mean?
There are more photons
200
The higher energy photons strike electrons in the metal when which characteristic of a wave is increased?
Frequency
200
What is a blackbody?
An object which absorbs all the EM radiation it receives. It is also a perfect emitter; it radiates all this absorbed energy back out.
300
What is energy measured in in Planck's equation.
Quanta
300
yes
Is it possible for photons to go through an atom without being absorbed by an electron
300
What happens to the speed of the electrons leaving as the intensity of the light increases?
It remains the same
300
What happens if there is a very low amount of light frequency?
No electrons are ejected no matter how much you increase the intensity
300
What are the two ways electrons emitted from metal are measured?
The number of electrons emitted and the speed of the emitted electrons.
400
What does the Quantum Field Theory state?
All matter and energy travel like a wave but hit like a particle.
