Visible Light Spectrum

Front

What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 380 nanometers (violet) to 750 nanometers (red).

Front

What color of light has the longest wavelength?

Back

Red light has the longest wavelength in the visible light spectrum.

Front

What color of light has the shortest wavelength?

Back

Violet light has the shortest wavelength in the visible light spectrum.

Front

What is wavelength?

Back

Wavelength is the distance between successive peaks of a wave, typically measured in nanometers (nm) for light.

Front

How does the wavelength of light affect its color?

Back

Different wavelengths of light correspond to different colors; longer wavelengths appear red, while shorter wavelengths appear violet.

Front

What happens to light when it passes from air into water?

Back

Light rays are bent (refracted) when they pass from air into water, which can cause objects to appear distorted or broken.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, due to a change in its speed.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelength and highest energy, found beyond the visible light spectrum.

Front

What is the order of the electromagnetic spectrum from longest to shortest wavelength?

Back

Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.
