2025\2026; Brand New Actual Exam Questions
With Answers
Physics - correct-answer-The study of forces, energy, motion
transverse wave - correct-answer-Wave where the oscillation is perpendicular to
the direction the wave is traveling
longitudinal wave - correct-answer-Wave where the oscillation occurs along the
direction the wave is traveling
electromagnetic waves - correct-answer-Waves with both an electric and
magnetic component. Can only be transverse waves and can travel through a
vaccuum
compression - correct-answer-Region of longitudinal wave where particles are
close together
,2|Page
expansion - correct-answer-Region of longitudinal wave where particles are far
apart (aka rarefaction)
crest - correct-answer-The highest point in a wave above equilibrium
trough - correct-answer-The lowest point in a wave under equilibrium
amplitude - correct-answer-The distance between a wave's equilibrium and
crest/trough in a transverse wave, or how compressed/expanded the medium
becomes in a longitudinal wave
wavelength - correct-answer-The horizontal distance after which the wave repeats
period - correct-answer-The amount of time needed for one full oscillation/one
wave to pass
, 3|Page
frequency - correct-answer-Number of wave oscillations in a given period of time
sound wave - correct-answer-A disturbance we can hear that moves through a
medium away from the source
Matter - correct-answer-Anything that takes up space and has mass
Atom - correct-answer-The basic building block of matter
valence electrons - correct-answer-The electrons in the outer most shell of an
atom
Element - correct-answer-A pure substance made of only one kind of atom,
defined by its proton count
atomic number - correct-answer-The number of protons in the nucleus of an atom
