Mechanical and Electromagnetic 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. Examples include radio waves, microwaves, X-rays, and gamma rays.

What is the relationship between wavelength and energy in waves?

Back

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

Front

What are X-rays used for?

Back

X-rays are used in medical imaging to see inside the body, particularly to view the skeletal system.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What does amplitude refer to in a wave?

Back

Amplitude refers to the maximum extent of a wave's displacement from its rest position, indicating the wave's energy.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What type of waves are radio waves?

Back

Radio waves are a type of electromagnetic wave used for communication.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (the speed of light).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.
