Waves & Electromagnetic Spectrum

Front

What is wavelength?

Back

The length of a wave from crest to crest or trough to trough.

Front

What is refraction?

Back

Refraction is when light bends as it passes from one medium to another.

Front

Which type of electromagnetic wave has the shortest wavelength?

Back

Gamma Rays have the shortest wavelength and the highest frequency/most energy.

Front

How is the electromagnetic spectrum divided?

Back

The electromagnetic spectrum is divided into regions by wavelength.

Front

What happens during reflection?

Back

Reflection is when light bounces off a surface.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength decreases, frequency increases, and vice versa.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

What are the main regions of the electromagnetic spectrum?

Back

The main regions include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye.

Front

What is the principle of superposition in waves?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.
