what are waves
100
A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to.
What is crest
100
Transverse waves are always characterized by particle motion being perpendicular to wave motion.
how does a compression wave travel?
100
The matter in the filament of a light bulb emits light when it is excited by an electrical current. The term that we use for emitting energy from matter is called radiation. Radiation is often referred to as electromagnetic radiation because the emitting energy has both electrical and magnetic properties
what creates a light wave?
100
the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
What is wavelength?
100
a wave vibrating at right angles to the direction of its propagation.
What is a transverse wave?
200
Waves have moving crests (or peaks) and troughs. A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to.
What is trough
200
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
how does a compressional wave travel?
200
Electromagnetic waves are formed by the vibrations of electric and magnetic fields. These fields are perpendicular to one another in the direction the wave is traveling. Once formed, this energy travels at the speed of light until further interaction with matter.
how are electromagnetic waves created?
200
the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
What is pitch?
200
compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium
What is a compression wave?
300
A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
What is rarefaction
300
Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner.
how does sound wave travel?
300
Sound is produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.
how are sound waves created?
300
the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
What is frequency
300
a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
What is sound waves?
400
The amplitude of an ocean wave is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water.
What is amplitude
400
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space.
how does light waves travel?
400
Mechanical waves can be produced only in media which possess elasticity and inertia. A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred.
how are mechanical waves created?
400
Wave height is a term used by mariners, as well as in coastal, ocean and naval engineering.
What is wave height
400
Electromagnetic waves are waves which can travel through the vacuum of outer space.
What is electromagnetic waves?
500
A compression is a region in a longitudinal wave where the particles are closest together.
What is compression
500
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
how does a electromagnetic wave travel?
500
Radio waves have frequencies from 3 THz to as low as 3 kHz, and corresponding wavelengths ranging from 100 micrometers (0.0039 in) to 100 kilometers (62 mi). Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are made by lightning, or by astronomical objects.
how are radio waves created?
500
the strength and vitality required for sustained physical or mental activity
What is energy?
500
an electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication.
What is radio waves?
