Sentence: an electromagnetic wave is a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light

electromagnetic wave
a wave in which the particles of the medium move perpendicular to the direction the wave is traveling

Sentence: a transverse wave is a wave in which the particles of the medium move perpendicular to the direction the wave is traveling

transverse wave
a wave in which the particles of the medium vibrate parallel to the direction of wave motion

Sentence: a longitudinal wave is a wave in which the particles of the medium vibrate parallel to the direction of wave motion

longitudinal wave
the highest point of a wave

Sentence: a crest is the highest point of a wave

Crest
the lowest point of a wave

Sentence: a trough is the lowest point of a wave

trough
the maximum distance that the particles of a wave’s medium vibrate from their rest position

Sentence: amplitude is the maximum distance that the particles of a wave’s medium vibrate from their rest position

amplitude
the distance from any point on a wave to an identical point on the next wave

Sentence: wavelength is the distance from any point on a wave to an identical point on the next wave

wavelength
in physics, the time that it takes a complete cycle wave oscillation to occur

Sentence: a period, in physics, the time that it takes a complete cycle wave oscillation to occur

period
the number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time

Sentence: frequency is the number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time

frequency
an observed change in the frequency of a wave when the source or observer is moving

Sentence: the doppler effect is an observed change in the frequency of a wave when the source or observer is moving

Doppler effect
the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go thorugh

Sentence: Reflection is the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go thorugh

Reflection
a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening

Sentence: Diffraction is a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening

diffraction
the bending of a wave front as the wave front passes between two substances in which the sped of the wave differs

Sentence: refraction is the bending of a wave front as the wave front passes between two substances in which the sped of the wave differs

refraction
the combinations of two or more waves that results in a single wave

Sentence: interference is the combinations of two or more waves that results in a single wave

interference
a superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves

Sentence: constructive interference is a superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves

constructive interference
a superposition of two or more waves that produces an intensity equal to the difference of the individual waves.

Sentence: Destructive interference standing is a superposition of two or more waves that produces an intensity equal to the difference of the individual waves.
