Benchmark 2 Review

Front

What is a wave trough?

Back

The lowest point of a wave, where the wave dips down.

Front

Which electromagnetic wave has the lowest frequency?

Back

Microwave.

Front

What is wavelength?

Back

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 diffraction?

Back

The bending of waves around obstacles or through openings, allowing sound to be heard around corners.

Front

How does amplitude relate to energy in a wave?

Back

A wave with high amplitude carries high energy.

Front

What is frequency in the context of waves?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is the speed of a wave?

Back

The distance a wave travels in a given amount of time, calculated as speed = wavelength × frequency.

Front

What is an electromagnetic wave?

Back

A wave that can travel through the vacuum of space, consisting of oscillating electric and magnetic fields.

Front

What are the different types of electromagnetic waves?

Back

They include gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.
