WGU C165 INTEGRATED PHYSICAL SCIENCES
COMPREHENSIVE TEST 2026 COMPLETE
QUESTIONS AND SOLUTIONS 100% CORRECT
◉ wave. Answer: A disturbance that transfers energy from place to
place
◉ oscillation. Answer: the act or state of swinging back and forth
with a steady, uninterrupted rhythm
◉ Equilibrium. Answer: A state of balance
◉ medium. Answer: The material through which a wave travels is
called a
Gases (air), liquids, solids
◉ mechanical wave. Answer: A wave that requires a medium
through which to travel
◉ electromagnetic waves. Answer: A form of energy that can move
through the vacuum of space.
,◉ transverse wave. Answer: A wave that moves the medium in a
direction perpendicular to the direction in which the wave travels
◉ longitudinal wave. Answer: A wave in which the vibration of the
medium is parallel to the direction the wave travels. Compressed
◉ Compression. Answer: The part of a longitudinal wave where the
particles of the medium are close together.
◉ expansion. Answer: an increase in the volume of a substance
while its mass remains the same. Expansion is usually due to
heating. When substances are heated, the molecular bonds between
their particles are weakened, and the particles move faster, causing
the substance to expand.
◉ Rarefaction. Answer: The part of a longitudinal wave where the
particles of the medium are far apart
◉ Wavelength. Answer: The distance between two corresponding
parts of a wave
◉ Frequency. Answer: the number of complete wavelengths that
pass a point in a given time
, ◉ Amplitude. Answer: the height of a wave's crest or how intense
◉ Crest. Answer: Highest point of a wave (peak)
◉ Trough. Answer: lowest point of a wavelength
◉ Period of a wave. Answer: Time for one complete waveform to
travel
◉ electromagnetic spectrum. Answer: All of the frequencies or
wavelengths of electromagnetic radiation
◉ radio waves. Answer: Electromagnetic waves with the longest
wavelengths and lowest frequencies
◉ microwave. Answer: very short electromagnetic wave; microwave
oven (oven that cooks quickly by using microwaves)
◉ Infrared. Answer: Electromagnetic waves of frequencies lower
than the red of visible light.
◉ visable light. Answer: portion of the electromagnetic spectrum
that is visible to the human eye.
