Words
A ____ is a disturbance that transfers energy trough matter or space, usually in the form of oscillations or vibrations.
Wave
The ______ is the lowest point of a transverse wave.
Trough
_________ is the maximum distance that the particles of the wave’s energy and intensity.
Amplitude
A ___________ material scatters light as it passes through, allowing some light through but not clear enough to see detailed images.
Translucent
· Solid (slowest)
· Liquid
· Gas (fastest)
Light waves
__________ ____ require a medium( solid, liquid, or gas) to travel. They cannot move through a vacuum.
Mechanical waves
In a ____________ ____, particles of the medium move parallel to the direction of wave propagation. Sound waves in air are a common example.
Longitudinal wave
__________ is the distance between two consecutive crests or troughs in a transverse wave length.
Wavelength
An ______ material does not allow any light to pass through, preventing objects from being seen through it.
Opaque
· Solid (fastest)
· Liquid
· Gas (slowest)
Sound waves
A ______ is a substance or material(e.g., water, air, or solid object) through which a wave travels.
Medium
___________ in a longitudinal wave is where particles are pushed closer together. This is the high-pressure area of the wave.
Compression
________ refers to the number of waves that pass a given point in a unit of time, typically expressed in hertz(hz).
Frequency
__________ occurs when waves bounce back from a surface. This is commonly seen with light waves hitting a mirror.
Reflection
In a __________ ____, the particles of the medium move perpendicularly to the direction of the wave. Examples include water waves and em waves.
Transverse wave
___________ is the part of a longitudinal wave is where particles are spread apart, representing the low pressure area.
Rarefaction
__________ is when a wave is taken up by a material and usually converted to heat, as opposed to being reflected or transmitted.
Absorption
__________ is the bending of light as it changes speed moving from one medium to another, such as from air to water.
Refraction
The _____ is the highest point of a transverse wave.
Crest
__ _____ can travel trough the vacuum of space and do not require a medium. They include light, radio waves, and x-rays.
Em waves
A __________ material allows light to pass through with little to no obstruction, making objects behind it clearly visible.
Transparent
The speed at which light waves travel through different materials. Light moves fastest in empty space but slows down a bit in air, water, or glass.
