In a Venn diagram of the wave properties and particle properties of EM
radiation, which explanation belongs in the overlapping part? - 🧠ANSWER
✔✔can be used to model transfer of energy
Consider the two statements below. Which statement can be evaluated
with a current understanding of the wave model?
Statement 1: When EM radiation passes through a narrow slit, interference
patterns are observed.
Statement 2: When EM radiation hits a piece of metal, electrons are
released. - 🧠ANSWER ✔✔Statement 1, because waves add to or cancel
each other and cause interference patterns
A scientist observes that EM radiation bounces off a surface in a
predictable manner. Which model of EM radiation can be used to evaluate

, this observation? - 🧠ANSWER ✔✔The behavior of the EM radiation
resembles ping-pong balls, so the particle model can explain this
observation.
Which option is a scientific claim about particles? - 🧠ANSWER ✔✔Particles
are distinct objects with a well-defined location and a single, distinct path.
What is a scientific claim? - 🧠ANSWER ✔✔a statement supported by
evidence and reasoning
Astronomers study galaxy motion by looking at the frequency of light
coming from the stars inside the galaxies. Which model of light would be
most useful in studying this phenomenon? - 🧠ANSWER ✔✔the wave
model of light
The wave and particle models are both important for understanding light.
Which statement describes a difference between the way waves and
particles act? - 🧠ANSWER ✔✔Two waves can cancel each other out, while
two colliding particles cannot.
Light undergoes refraction when it moves from one medium to another.
Light entering a medium at any angle of incidence besides 0 degrees will
change direction. Water waves do something similar when they change
