Electromagnetic Waves

Front

No medium is needed for the motion these waves all travel through space at the speed of light. (3.0x10^8)

Back

Standing wave

Front

a wave that appears to stand in one place, even though it is really two waves interfering as they pass through each other

Back

Equilibrium

Front

a state in which opposing forces or influences are balanced.

Back

Speed

Front

being a scalar quantity, is the rate at which an object covers distance.

Back

Longitudinal

Front

A wave in which the vibration of the medium is parallel to the direction the wave travels

Back

Mechanical wave

Front

Motion requires a material medium. Materials carry the energy of the ______ waves.

Back

Amplitude

Front

For a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position.

Back

Transverse

Front

Causes the particles of the medium to vibrate perpendicular to the direction of the motion of the wave

Back

Waves Move

Front

energy not matter

Back

Wavelength

Front

The distance between two corresponding parts of a wave

Back

Wave pulse

Front

a single disturbance that travels through a medium

Back

Reflection

Front

Bouncing off of something Ex: sun or moon visible on surface of lake

Back

Anti-Node

Front

Point of maximum displacement in a standing wave.

Back

Constructive

Front

When the wave pulses are in the same direction

Back

Crest

Front

Highest point of a wave

Back

Period

Front

Shortest time interval during which the motion repeats itself. (Seconds)

Back

Speed of light

Front

3.00 x 10^8 m/s the distance light can travel in a unit of time through a given substance

Back

Node

Front

A point on a standing wave that has no displacement

Back

Frequency

Front

Number of complete vibration per second. (HZ)

Back

Law of Superposition

Front

states that the displacement of a medium caused by 2 or more waves is the algebraic sum of the displacements caused by the individual waves

Back

Interference

Front

The combination of two or more waves that results in a single wave

Back

Trough

Front

Lowest point of a wave

Back

Destructive

Front

When you have 2 pulses with equal but opposite direction

Back
