Verified Answers||Graded A+
Wave -CORRECT ANSWER Rhythmic disturbance which carries energy through
matter or space.
Mechanical Wave -CORRECT ANSWER A wave that requires a medium through
which to travel
Medium -CORRECT ANSWER Material through which a wave travels
Transverse wave -CORRECT ANSWER A wave that moves the medium in a direction
perpendicular to the direction in which the wave travels
Compressional Wave -CORRECT ANSWER Matter in the medium moves back and
forth along the same direction that the wave travels
Wave frequency -CORRECT ANSWER The number of waves passing a fixed point per
second.
Hertz -CORRECT ANSWER Unit used to measure frequency
Wave period -CORRECT ANSWER How long it takes a wave to pass a point.
Reflection -CORRECT ANSWER The bouncing back of a wave when it hits a surface
through which it cannot pass.
Refraction -CORRECT ANSWER The bending of a wave as it enters a new medium.
Law of Reflection -CORRECT ANSWER the angle of incidence equals the angle of
reflection on a flat reflective surface.
Law of Refraction -CORRECT ANSWER As light passes from less dense medium into
more dense medium, it will slow and bend towards the normal. If the light ray passes
from more dense to less dense, it will speed up and bend away from the normal.
Diffraction -CORRECT ANSWER The bending of a wave as it moves around an
obstacle.
Wave Interference -CORRECT ANSWER Occurs when two or more waves meet while
traveling along the same medium.
, Constructive Interference -CORRECT ANSWER The interference that occurs when two
waves combine to make a wave with a larger amplitude.
Destructive Interference -CORRECT ANSWER The interference that occurs when two
waves combine to make a wave with a smaller amplitude.
Seismic Wave -CORRECT ANSWER Vibrations that travel through Earth carrying the
energy released during an earthquake
regular reflection -CORRECT ANSWER reflection from a smooth surface
diffuse reflection -CORRECT ANSWER reflection from a rough surface
Intesity -CORRECT ANSWER The amount of energy that flows through a certain area
in a specific amount of time
Loudness -CORRECT ANSWER The human perception of sound intensity
Pitch -CORRECT ANSWER How high or how low a sound seems to be
Ultrasonic -CORRECT ANSWER Sound frequencies above 20,000 Hz
electromagnetic spectrum -CORRECT ANSWER the range of wavelengths or
frequencies over which electromagnetic radiation extends.
distance -CORRECT ANSWER how far an object has moved
displacement -CORRECT ANSWER the distance and direction of an objects change in
position from the starting point.
speed -CORRECT ANSWER distance an object travels per unit of time.
average speed -CORRECT ANSWER total distance traveled divided by the amount of
time traveled
velocity -CORRECT ANSWER the speed of an object and the direction of its motion.
acceleration -CORRECT ANSWER the rate of change of velocity.
net force -CORRECT ANSWER when two or more forces act on an object at the same
time, the forces combine to make this
inertia -CORRECT ANSWER the tendency of an object to resist any change in its
motion (Newton's first law).
force -CORRECT ANSWER a push or pull on an object
