Mechanical and Electromagnetic Waves Flashcard

Front

What are waves that do NOT require a medium to travel?

Back

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

Front

What type of rays have shorter wavelengths than infrared and can cause sunburn?

Back

Ultraviolet Rays are a type of electromagnetic radiation with wavelengths shorter than visible light, known for causing sunburn.

Front

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

Back

Radio Waves have the least energy in the electromagnetic spectrum.

Front

What does the distance between two consecutive peaks of a wave represent?

Back

Wavelength is the distance between two consecutive peaks (or troughs) of a wave.

Front

What is the area of a longitudinal wave where the particles are FAR apart called?

Back

Rarefaction is the region in a longitudinal wave where particles are spread apart.

Front

What are the two main types of mechanical waves?

Back

The two main types of mechanical waves are longitudinal waves and transverse waves.

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 longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the direction of the wave, while in transverse waves, particles move perpendicular to the direction of the wave.

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 (or about 300,000 km/s).

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.
