Waves
Correct Answer:
Oscillation or periodic movement that can transport energy from one
point space to another
Electromagnetic Waves
Correct Answer:
Consist of an electric and magnetic field, oscillating perpendicular to
one another as well as the direction of travel
Wavelength
Correct Answer:
- Distance between two consecutive peaks or troughs in a wave
- Measured in meters
Frequency
Correct Answer:
- Number of wave cycles (complete wavelengths) that pass a
specified point in space in a specified amount of time
- Measured in hertz, Hz (cycles per second, 1/s or s^-1)
Amplitude
Correct Answer:
,Magnitude of the wave's displacement, which is one half the height
between the peaks and troughs
Electromagnetic Spectrum
Correct Answer:
Range of energies that electromagnetic radiation can comprise,
including radio, microwaves, infrared, visible, ultraviolet, x-rays and
gamma rays
Isaac Newton
Correct Answer:
When trying to separate the colors of light it went in a straight line
the way particles do so light was made of particles
Christian Huygens
Correct Answer:
Reflection and refraction leading him to saying light was waves
Thomas Young
Correct Answer:
- Double slit experiment
- Light shown through both slits should have appeared as two line of
viewing screen but instead their were multiple lines showing that
Light was made of waves
James Clerk Maxwell
Correct Answer:
- Light is made of two waves; electric and magnetic field
- First colored photo
Two Domains Scientists View the Physical Universe as
Correct Answer:
,- Matter
- Electromagnetic Radiation
Matter
Correct Answer:
Composed of particles moving according to Newton's laws of motion
Electromagnetic Radiation
Correct Answer:
- Consists of waves governed by Maxwell's equations
- Paradoxes prevented full explanation under either framework
Wave Particle Duality
Correct Answer:
Observation that elementary particles can exhibit both wave-like and
particle-like properties
Black Body Radiation
Correct Answer:
- Appear black because they absorb all wavelengths of light and emit
energy when heated
- When it emits light when in the visible range it shows the temp
UV Catastrophe
Correct Answer:
Inability to see energy emitted by black body radiation
Photoelectric Effect
Correct Answer:
If you shoot light of a certain energy at a metal, electrons would be
ejected off the metal. If the energy was higher than required it would
eject at a higher speeder but if not enough nothing would happen.
, Einstein found that intensity had no effect on speed of ejection but
frequency did therefore particle behaviour
Einstein Equation
Correct Answer:
Only calculates the energy of one photon of light at a given
frequency or wavelength
Photon
Correct Answer:
- Smallest possible packet of electromagnetic radiation
- A particle of light whose energy depends on frequency
Bohr Model
Correct Answer:
- Planetary model was flawed because electrons would be attracted
to the nucleus and would get closer till it collided
- Treated particles as particles and waves
- Electrons could absorb or emit energy
- Only works for hydrogen
Energy States in Atoms
Correct Answer:
- Ground state
- Excited state
Ground State
Correct Answer:
State where electrons in an atom, ion or molecule have the lowest
energy possible
Excited State
Correct Answer:
