Waves and Communication Flashcard

Front

What causes us to perceive different colors in white light?

Back

Different wavelengths of light cause us to perceive individual colors.

Front

What type of wave requires a medium to travel?

Back

Mechanical wave.

Front

What is the visible spectrum?

Back

The range of colors in white light.

Front

Define a wave.

Back

A disturbance that causes a regular pattern of motion.

Front

What is refraction?

Back

The phenomenon when a wave changes direction as it passes from one medium to another.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is a transverse wave?

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave.

Front

What is a longitudinal wave?

Back

A wave in which the motion of the medium is parallel to the direction of the wave.

Front

What is amplitude in the context of waves?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the speed of a wave?

Back

The distance a wave travels per unit of time.
