8PS Unit 7 Wave Properties and Electromagnetic Radiation

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

pitch

• a tone's experienced highness or lowness; depends on frequency

• the loudness of a sound

• the duration of a sound

• the quality of a sound

electromagnetic spectrum

• A range of sound frequencies

• All of the frequencies or wavelengths of electromagnetic radiation

• A type of visible light

• The speed of light in a vacuum

analog signal

• A type of signal where the data is represented by continuous waves.

• A type of signal that is either on or off.

• A type of signal that can only be transmitted over short distances.

• A type of signal that is represented by discrete values.

absorption

• takes place when matter captures electromagnetic radiation

• is the process of emitting light

• occurs when light is reflected off a surface

• is the process of converting sound into energy

amplitude

• Height of a wave

• Width of a wave

• Frequency of a wave

• Speed of a wave

sound insulation

• the ability of a barrier to prevent sound from reaching a receiver.

• the process of amplifying sound waves.

• the measurement of sound frequency in a given environment.

• the technique used to enhance sound quality in recordings.

visible light

• electromagnetic waves that are visible to the human eye

• sound waves that can be heard by humans

• radio waves used for communication

• ultraviolet rays that cause sunburn

reflection

• The bending of a wave as it passes through different mediums.

• The bouncing back of a wave when it hits a surface through which it cannot pass.

• The absorption of a wave by a surface.

• The scattering of a wave in multiple directions.

wave

• A disturbance that transfers energy from place to place

• A type of particle that moves through a medium

• A fixed point in space

• A measure of frequency in sound waves
