Which Wavelength Is Longer Red Or Blue?

What wavelength is dangerous?

Ultraviolet (UV) (Wavelength 10-7 – 10-8 meters) UV-C rays are the most harmful and are almost completely absorbed by our atmosphere.

UV-B rays are the harmful rays that cause sunburn..

Why does red have a longer wavelength?

Red light has a slightly longer wavelength than blue light. … Notice that as wavelength increases, frequency decreases. But there are waves with higher frequencies (shorter wavelengths) than blue light and waves with lower frequencies (longer wavelengths) than red light.

How do you know which wavelength is longer?

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.

What color has highest frequency?

violetWhen it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.

Which Colour bends the most?

violet lightEach beam of light, with its own particular wavelength (or color), is slowed differently by the glass. Since violet light has a shorter wavelength, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while red light is bent the least.

What color is lowest in energy?

RedThe frequency of the radiation is proportional to its energy and the wavelength of the radiation is inversely proportional to the energy. Red is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.

What are the 7 types of waves?

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.

Which color wavelength is the longest?

RedWe see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.

Which color has the strongest wavelength?

RedWe see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.

What color has lowest frequency?

RedRed has the longest wavelength, the shortest frequency, and the lowest energy.

Why do we see red sunsets?

At sunrise and sunset, the Sun is very low in the sky, which means that the sunlight we see has travelled through a much thicker amount of atmosphere. … The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light.

What color has the shortest wavelength?

violet lightOn one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
