Front

What is the order of electromagnetic waves from low to high frequency?

Back

Radio, Microwave, Infrared, Visible, Ultraviolet, X-rays, Gamma.

Front

Which type of transverse wave has the highest frequency?

Back

Gamma rays.

Front

What is the term for the matter (solid, liquid, or gas) through which waves can travel?

Back

Medium.

Front

What does the demonstration with a slinky and a styrofoam cup illustrate about sound waves?

Back

It demonstrates the reflection of sound waves.

Front

What type of waves require a medium to pass?

Back

Mechanical Waves.

Front

What are the characteristics of electromagnetic waves?

Back

They do not require a medium and can travel through a vacuum.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel to the direction of wave travel.

Front

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

Back

Approximately 343 meters per second.

Front

What is the relationship between frequency and wavelength in waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the phenomenon called when a wave changes direction as it passes from one medium to another?

Back

Refraction.
