Chapter 8 Flashcards
First assessment review (section 2-6)
Light
Electromagnetic Radiation, type of energy embodied in oscillating electric and magnetic fields
Wavelength of Light
Determines its color (red-blue, longest to shortest)
Amplitude of Light
determines its brightness/intensity
Frequency
Number of cycles that pass through a point through a given time [frequency=speed/wavelength]
Photon [quantum]
packet of light
De Broglie Wavelength
wavelength of an electron of mass moving at a velocity [wavelength=Planck’s constant/mass*velocity]
Nature tends towards states with
Low potential energy
Electrons have lower potential energy when they are
closer to the nucleus
When forced together, an electrons’ potential energy
rises
Higher energy light waves have higher
frequency
what is being emitted by atoms inside?
only certain amounts of energy
