This physicist demonstrated the Photoelectric Effect and observed that when light is made to shine on a metal, it leaks electric charge.
Who is Heinrich Hertz
100
Originally light was thought to be one continuous
What is wave
100
The electrons absorb the ________ energy, giving them enough energy to escape the nucleus's hold.
What is a photon?
100
Planck's basic energy equation.
What is E = h v?
100
360 Watts
What is a light bulb

This English physicist's famous double slit experiments showed that light interferes with itself, similar to water waves.
Who is Thomas Young
200
This prevents light of a wavelength shorter than a certain UV wavelength from reaching your skin
What is sunscreen
200
Like a gas, light is made up of _________.
What are particles?
200
This absorbs all the EM radiation that it receives. It also radiates it back out.
What is blackbody radiation?
200
These are used to read the screen
What are your eyes

This Hungarian- German physicist's Photoelectric Effect tests showed that by increasing the frequency of the light source, the electrons fly off the metal with greater energy.
Who is Phillip von Lenard
300
When the frequency of the light is low enough ____ electrons are ejected, no matter how intense the light
What is no or zero
300
Light is made of individual packets or _________ of energy.
What is a quanta?
300
This aspect of light is always fixed, no matter how much you increase the incoming light's intensity.
What is speed?
300
Old fashion iPods
What is a transistor radio
400
This physicist proposed that the energy of these photons of light is given by Planck's equation E=hv
Who is Albert Einstein
400
This aspect of the wave changes the color of the light
What is frequency
400
The light emitted from something hot, like a light bulb filament, has the same distribution as this.
What is a gas?
400
A more intense light beam means more of these.
What are photons?
400
Electronic equipment fabricated to carry out a number of electronic functions in an integrated circuit
What is a silicon chip
500
This French physicist hypothesized that any particle should exhibit the wave-particle duality of light and concluded that the velocity of a particle should always equal the group velocity of the corresponding wave. He also found that the magnitude of the group velocity is equal to the particle's speed.
Who is Louis de Broglie
500
This theory explains that all matter and energy travel like a wave but hit like a particle
What is the Quantum Field Theory
500
Light is special because it has this, which nothing else has.
What is wave-particle duality?
500
1.05 X 10^-27
What is Planck's constant?
500
These are being created today to replace the computers we use today
