Electromagnetic Radiation form of energy that has wavelike behavior as it travels through spave
Electromagnetic Spectrum All the forms of electromagnetic radiation
Wavelength distance between corresponding points on adjacent waves
Frequency (v) number of waves that pass a given point in a specific time, usually one second (described as waves/second called hertz)
photoelectric effect emission of electrons from a metal when light shines on the metal
quatntum energy that is the minimum quantity of energy that can be lost or gained by an atom (E is the energy in Joules)
Planck's constant h=6.626x10-34th Jxs
electromagnetic radiation equation c(speed)= /\(wavelength)x v (frequency)
Photon particle of electromagnetic radiation having zero mass and carrying a quantum energy
ground state lowest energy state of an atom
excited state atom has a higher potential energy than it has at ground state
continuous spectrum emission of continuous range of frequencies of electromagnetic radiation
Niels Bohr proposed a hydrogen atom model that linked the atoms electron to photon emission (Plum pudding!!)
Heisenberg uncertainty principle states that its impossible to determine simultaneously both the position and velocity of an electron or any other particle
Quantum Theory describes mathematically the wave properties of electrons and other very small particles
orbital three dimensional region around the nucleus that holds electrons

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
