AND REACTIONS REVIEW QUESTIONS
ANSWERS VERIFIED GUIDE
◉ limiting reactant/reagent.
Answer: amount of one of the reactants which limits how much
product can be formed. smallest amount.
◉ percent yield.
Answer: actual/theoretical x 100
◉ electromagnetic radiation.
Answer:
◉ wavelength.
Answer: The distance between two corresponding parts of a wave.
seconds/wave. 1/frequency. measured in m
◉ amplitude.
Answer: Height of a wave
, ◉ frequency.
Answer: waves/second. 1/wavelength. measured in Hz
◉ Constant (c).
Answer: 3 x 10^8 m/s. c=(wavelength)(frequency)
◉ constructive interference.
Answer: The interference that occurs when two waves combine to
make a wave with a larger amplitude = brighter
◉ destructive interference.
Answer: The interference that occurs when two waves combine to
make a wave with a smaller amplitude = darker
◉ diffraction.
Answer: The bending of a wave as it moves around an obstacle or
passes through a narrow opening
◉ models of light.
Answer: light as a wave/particle
◉ photoelectric effect.
