8PS Wave Properties and Electromagnetic Radiation

electromagnetic wave

• A form of energy that can move through the vacuum of space.

• A type of sound wave that travels through air.

• A wave that requires a medium to propagate.

• A wave that is only found in electrical circuits.

wavelength

• Horizontal distance between the crests or between the troughs of two adjacent waves

• The speed of a wave multiplied by its frequency

• The amplitude of a wave measured from the rest position

• The time it takes for one complete wave to pass a given point

amplitude

• Height of a wave

• Width of a wave

• Frequency of a wave

• Speed of a wave

refraction

• The bending of a wave as it passes at an angle from one medium to another

• The reflection of a wave when it hits a barrier

• The absorption of a wave by a medium

• The scattering of a wave in different directions

vacuum

• A space where no particles of matter exist

• A region filled with air and gases

• A type of cleaning device

• A state of matter with high density

electromagnetic spectrum

• All of the frequencies or wavelengths of electromagnetic radiation

• A type of sound wave

• A measure of electrical resistance

• The range of visible light only

digital signal

• A signal that encodes information as a string of 1's and 0's

• A signal that varies continuously over time

• A signal that can only be transmitted over analog channels

• A signal that represents physical quantities in a linear format

encode

• convert (information or an instruction) into a particular form.

• to decode information into a readable format.

• to compress data for storage efficiency.

• to encrypt data for security purposes.

mechanical wave

• A wave that requires a medium through which to travel

• A wave that can travel through a vacuum

• A wave that is produced by electromagnetic fields

• A wave that does not require any medium

sound wave

• a type of electromagnetic wave that travels through a vacuum

• a longitudinal wave that is caused by vibrations and that travels through a material medium

• a transverse wave that does not require a medium to travel

• a wave that is produced by the movement of electric charges
