Mechanical and Electromagnetic Waves Flashcard

Front

What are microwaves used for?

Back

Microwaves are used for heating food and are a type of electromagnetic wave with longer wavelengths than infrared.

Front

How does wavelength relate to energy in waves?

Back

A wave with a shorter wavelength has more energy than one with a longer wavelength.

Front

What does Point A represent in a wave diagram?

Back

Point A represents the crest of the wave.

Front

What type of waves do not require a medium to travel?

Back

Electromagnetic waves do not require a medium to travel.

Front

What do radio waves, microwaves, X-rays, and gamma rays have in common?

Back

They are all types of electromagnetic waves.

Front

Define electromagnetic waves.

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium.

Front

What is the relationship between frequency and wavelength?

Back

Higher frequency waves have shorter wavelengths, while lower frequency waves have longer wavelengths.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the direction of wave travel, while in longitudinal waves, the particle movement is parallel to the direction of wave travel.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.
