Which color of the visible spectrum has the shortest wavelength 400 nm

Visible light is the only part of the electromagnetic spectrum which is visible to the human eye. The human eye is not able to see the radiations with wavelengths outside this visible spectrum. Visible light can be seen in the form of different colors, each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the colors of light are seen together, they make white light.

When the white light is sends through a prism, it splits into the different colors after it passes through the prism. These different colors of light have different wavelengths.

The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight from the objects around us.The color of an object that we see is the color of light reflected from the object and the remaining all colors are absorbed.The wavelengths of the visible light is ranging from 400 to 700 nanometers (nm).

Different animals are sensitive to different wavelengths, for example snakes are sensitive to infrared wavelengths so they can detect infrared light and some insects can detect ultraviolet light.

Different colors of visible light

The different colors of visible light are

Violet light
Indigo light
Blue light
Green light
Yellow light
Orange light
Red light

Violet light

Violet light is present at the end of the visible light spectrum between indigo and the invisible ultra violet light. The wavelength of the visible violet light is about 400 nm (nanometers). It has the shortest wavelength than the other visible light colors. The violet colored objects are the objects that reflect the violet light and observes all the other colors of light.

The objects which reflect violet light are frequently appear as black because human eye is some what insensitive to the wavelength of violet light.

Indigo light

The wavelength of the visible indigo light is about 445 nm (nanometers). The indigo colored objects are the objects that reflect indigo colored light and observe all the other colors of light. When this indigo color light reaches our eyes, the object appeared in indigo color.

Blue light

The wavelength of the blue light is ranging from 450 to 495 nm (nanometer) and frequencies are ranging from 606 to 668 THz.

The blue colored objects are the objects that reflect blue colored light and observe all the other colors of light. When this blue color light reaches our eyes, the object appeared to be in blue color.

Green light

The wavelengths of the green light are ranging from 495 to 570 nanometers and frequencies are ranging from 526 to 606 THz. The green colored objects are the objects that reflect green colored light and observe the all other colors of light. When this green color light reaches our eyes, the object appeared to be in green color.

Yellow light

The yellow light has wavelengths ranging from 570 to 590 nanometers and frequencies ranging from 508 to 526 THz. The yellow colored object is the object that reflects yellow colored light and observes all the other colors of light. When this yellow color light reaches our eyes, the object appeared in yellow color.

Orange light

The orange light has wavelengths ranging from 590 to 620 nanometers and frequencies ranging from 484 to 508 THz. The orange colored objects are the objects that reflect orange colored light and observe all the other colors of light. When this orange color light reaches our eyes, the object appeared in orange color.

Red light

The red light has wavelengths ranging from 620 to 700 nanometers and frequencies ranging from 400 to 484 THz. The red colored objects are the objects that reflect red colored light and observe all the other colors of light. When this red color light reaches our eyes, the object appeared in red color.

Advantages

The main advantage of visible light is that you can see it.

Visible light is not harmful to our eyes.

Which color of the visible spectrum has the shortest wavelength 400 nm )?

The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is red and the shortest is violet.

What color has a wavelength of 400 nm?

Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*10¹⁴ Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*10¹⁴ Hz.

Is 400 nm a short wavelength?

The longest red waves are about 700 nanometers long. The shortest purple waves are 400 nanometers long. Light waves with short wavelengths carry more energy than ones with long wavelengths. "Light" waves shorter than 400 nm are called "ultraviolet" or "UV" light.
