PS.6.3.2 Waves Flashcard

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through the vacuum of space and consist of oscillating electric and magnetic fields. They include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which electromagnetic waves have the highest energy?

Back

Gamma rays have the highest energy among electromagnetic waves.

Front

What is pitch in sound?

Back

Pitch is the characteristic of sound that describes how high or low a sound is, determined by the frequency of the sound wave.

Front

What happens to a wave when it hits a surface it cannot pass through?

Back

The wave bounces back, a phenomenon known as reflection.

Front

What type of electromagnetic waves can humans see?

Back

Humans can see visible light, which is a small part of the electromagnetic spectrum.

Front

What is intensity in the context of waves?

Back

Intensity is the rate at which energy is transferred per unit area, often associated with the loudness of sound or brightness of light.

Front

What is the term for the distance between two consecutive peaks of a wave?

Back

Wavelength is the term for the distance between two consecutive peaks of a wave.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch, while lower frequency corresponds to a lower pitch.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, changing speed.

Front

What is absorption in terms of waves?

Back

Absorption is the process by which a wave's energy is taken in by a material, rather than being reflected or transmitted.
