Electromagnetic Radiation Online
Practice EXAM TEST 2025/2026
Scientists claim that electromagnetic radiation sometimes behaves like a wave with frequency
and wavelength. Which part of this claim needs to be further evaluated? - ✔✔✔the situations in
which the wave model would be useful to describe electromagnetic radiation
Which statement is a valid scientific claim? - ✔✔✔Interference patterns are best described by
using the wave model of electromagnetic radiation.
Which statement is an accurate description of how the wave model and the particle model of
light are used by scientists? - ✔✔✔The wave model is better in some situations, and the particle
model is better in others.
Which phenomenon is best explained by the particle model of light? - ✔✔✔the photoelectric
effect
Scientists have gathered large amounts of evidence on how light acts in different situations.
Where does reasoning from that evidence lead them? - ✔✔✔Reasoning leads them to models,
laws, and theories that are supported by the evidence.
Why do scientists use both the wave and particle models of light? - ✔✔✔Different observations
are better explained with reasoning from one model or the other.
The double-slit experiment, which shows interference patterns in electromagnetic radiation,
supports which theory? - ✔✔✔Electromagnetic radiation is composed of waves.
A scientist is conducting her own version of the double-slit test. Assuming the test is set up
properly, which observation could she make about the bands of light and dark fringes on the
screen? - ✔✔✔A series of light and dark bands appear on the screen.
Which model(s) of electromagnetic radiation is most suitable to describe the photoelectric
effect? - ✔✔✔particle model only
