Mechanical and Electromagnetic Waves Flashcard

Front

What are X-Rays?

Back

X-Rays are a type of electromagnetic radiation with a shorter wavelength than visible light, used primarily in medical imaging to view the skeletal system.

Front

What does wavelength represent in a wave?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

Front

What is compression in a longitudinal wave?

Back

Compression is the area in a longitudinal wave where the particles are close together, resulting in higher pressure.

Front

What is required for sound waves to travel?

Back

Sound waves require a medium (solid, liquid, or gas) to travel through; they cannot travel in a vacuum.

Front

Which part of the electromagnetic spectrum has the least amount of energy?

Back

Radio Waves have the least amount of energy compared to other parts of the electromagnetic spectrum.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium to travel through, such as sound waves and water waves.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium and can travel through a vacuum, such as light waves, X-rays, and radio waves.

Front

What is the difference between transverse and longitudinal waves?

Back

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

Front

What is rarefaction in a longitudinal wave?

Back

Rarefaction is the area in a longitudinal wave where the particles are spread apart, resulting in lower pressure.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.
