What type of visible light has the highest energy?

Back

Violet

Front

Put the EM waves in increasing frequency order: visible light, microwave, gamma.

Back

Radio, visible light, ultraviolet.

Front

How does light travel?

Front

What is the electromagnetic spectrum?

Back

The range of all types of EM radiation, including visible light, radio waves, microwaves, infrared, ultraviolet, x-rays, and gamma rays.

Front

What is reflection?

Back

The bouncing back of light when it hits a surface.

Front

What is the difference between regular and diffuse reflection?

Back

Regular reflection occurs on smooth surfaces, while diffuse reflection occurs on rough surfaces.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (km/s).

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as wavelength increases, frequency decreases.
