Light Podcast
The range of visible light is from ______nm to _______nm
Electromagnetic Spectrum
Electromagnetic radiation travels in a wave of energy called a photon.
Amplitude (how loud the sound is)
Wavelength
Velocity
Frequency
The speed of light (denoted with the variable c) = 3 x 108 m/s
High frequency _________ wavelength
Low frequency _________ wavelength
What makes the color or type of light change?
waves, such as x-rays and gamma rays, are more harmful than
waves.
Light and the Atom Podcast
When white light goes through a prism what colors does it make?
The atom has specific energy levels called ______________
As an electron falls, it produces a specific spectrum of ________
Light comes from electrons " _____________"
More specifically: electrons must first be _______________ and then they then "_________" back to a ________ energy
level
Electrons are ______________
This means that they can only have _____________ energies
Going to a higher energy level is called ________________
"Falling" is called ______________ of light
"Falling" from a ____________ level emits a higher energy of light
