Types of Waves
A(n) __________ is a disturbance that transfers energy from one place to another without transferring matter.
WAVE
The height of a wave is called its __________.
AMPLITUDE
What creates/ causes sound waves?
VIBRATIONS
What type of waves are light waves?
ELECTROMAGNETIC
What is the bouncing back of a light wave after it hits a surface?
REFLECTION
A _____________ is a wave in which the disturbance is perpendicular to the direction the wave travels
EX: A flag moving in the wind.
TRANSVERSE
The __________ of a wave is the distance between a point on one wave and the identical point of the next wave.
WAVELENGTH
What type of waves are sound waves?
LONGITUDINAL (Mechanical)
What is the bending of light wave as it passes from one medium into a different medium?
REFRACTION
The reason we see the colors of the rainbow (ROYGBIV) is because the colors of light travel at different ___________.
SPEEDS (FREQUENCIES)
_______________ waves move particles back and forth along the same direction (parallel) in which the waves travel.
LONGITUDINAL
For a wave, the larger the amplitude, the more ____________ the wave carries.
ENERGY
You see lightning before you hear thunder because light energy is _____________ than sound energy.
FASTER
(Speed of light = 300,000 km/s)
What electromagnetic waves have the highest frequency?
GAMMA RAYS
What are the three types of cones that are used to see color?
RED, GREEN, and BLUE
A(n) _______________ wave is a wave that travels only through matter (a medium), such as transverse waves and longitudinal waves.
EX: Seismic wave (earthquake), sound wave
MECHANICAL
What is the highest point and the lowest point of a transverse wave called?
CREST (highest point)
TROUGH (lowest point)
The speed of sound depends on the ______________ through which it is traveling.
MEDIUM (solid, liquid, gas)
Light has a "dual nature" because it can behave as _________ or __________.
WAVES or PARTICLES (photons)
______________ light is a mixture of all the colors of the visible spectrum.
WHITE
A(n) _______________ wave is a wave that can travel through a vacuum (empty space).
EX: Microwave, light wave, radio wave
ELECTROMAGNETIC
In a longitudinal wave, a ____________ is a region where the particles are close together; and a _____________ is a region where the particles are far apart.
COMPRESSION (close together)
RAREFACTION (far apart)
Describe the relationship between frequency and pitch.
HIGHER FREQUENCY = HIGHER PITCH
LOWER FREQUENCY = LOWER PITCH
The angle of reflection is equal to the angle of ________________.
INCIDENCE
The sky is blue because sunlight is _______________ by the air.
SCATTERED
