Frequent question: What has the longest wavelength in the electromagnetic spectrum?

Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 .

Which has the longest wavelength which has the highest frequency?

Gamma rays

What is the wavelength range of the electromagnetic spectrum?

The electromagnetic spectrum (EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10-18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 1026 Hz to 3 ×103 Hz.

Which range of the EM spectrum has the longest wavelength?

Radio waves

What are the 7 types of electromagnetic radiation?

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

What are the 7 types of electromagnetic spectrum?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

Which wavelengths can humans not see?

The human eye is not capable of “seeing” radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light.

Which has longest wavelength?


What can humans not see?

What Is Non-Visible Light? The human eye can only see visible light, but light comes in many other “colors”—radio, infrared, ultraviolet, X-ray, and gamma-ray—that are invisible to the naked eye.

What is the hottest color of light?


What color is the most powerful?


Why do we see red sunsets?

Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. … The result is that the sunlight takes on an orange or red cast, which we can see reflected from clouds or other objects as a colorful sunset (or sunrise).
