Let's dive in as you know Light is all around us in the colors we see,but do you know the technologies we use and even the signals that travel invisibly through the air all of thme are light as well?!😐 what we call light is just a small part of a much larger range of electromagnetic waves known as the light spectrum.
The light spectrum represents all types of electromagnetic radiation—waves of energy that travel through space at the speed of light.
These waves range from extremely short wavelengths (like gamma rays) to very long wavelengths (like radio waves).
Only a tiny portion of the spectrum — called visible light — can be detected by the human eye🙋🏻♂️.
Longest wavelengths, lowest frequencies and the least harmful type of radiation.
This type of wave is used mainly for broadcasting and communications.
Microwaves have the second longest wavelength and is used for radar, satellite communications, and microwave ovens.
Felt as heat.
Used in remote controls, thermal cameras, and night-vision devices.
This is the small slice humans can see with the naked eye — wavelengths from about 400 to 700 nanometers.
Invisible to humans,
As UV has such a short wavelength, its frequency is higher than visible light. Most of the light emitted by the Sun is UV
Responsible for sunburns.
Also used for sterilization and detecting counterfeit money.
X-rays have a very short wavelength.
X-rays are very penetrating and pass through soft tissue easily, but do not pass through bones. A common use of X-rays is by radiographers to check for broken bones in the bodies of human patients.
X-rays can also be used by airport security to check the insides of suitcases.
Gamma rays have the shortest wavelength of all of the EM radiations with the highest frequency.
As gamma rays are so penetrating they can cause damage to tissues below the surface of the skin. Gamma rays penetrate cells and can go through your skin and even your bones also cause their DNA to mutate which in turn can cause cancer.
Produced in nuclear reactions and extreme cosmic events.
The light spectrum is far more than just the colors we see. It’s a vast, powerful range of electromagnetic waves that influence everything from communication and medicine to astronomy and daily life.
