Wave Flashcard

Front

What is Rarefaction in a wave?

Back

It is the part of the wave where the particles are spread out.

Front

Which type of wave carries the most energy?

Back

X-rays have shorter wavelengths and can carry more energy than infrared light, visible light, and UV light.

Front

Why can't we hear sounds in outer space?

Back

Because there is no medium (like air) for sound waves to travel through.

Front

What type of interference occurs when a wave bounces off a surface?

Back

Reflection is the type of interference that occurs when a wave bounces off a surface.

Front

What is frequency measured in?

Back

Frequency is measured in Hertz (Hz).

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What is the difference between compression and rarefaction in a wave?

Back

Compression is where particles are close together, while rarefaction is where particles are spread out.

Front

What is wavelength?

Back

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

Front

What is the relationship between wavelength and energy?

Back

Shorter wavelengths carry more energy than longer wavelengths.

Front

What is the speed of sound in air?

Back

The speed of sound in air is approximately 343 meters per second at room temperature.
