The electromagnetic spectrum wasn't "developed"--it was discovered. The first person to started this discovery was William Herschel in 1799. He wanted to find out how light and heat were connected. Herschel used a prism to break up white light and then measured the temperature of each color. Violet had the loset reading, and red had the highest.
Then Wilhelm Ritter, in 1801, discovered ultraviolet light. Ritter dipped pieces of paper into silver nitrate. He shone a different-colored light on each strip, working his way through the rainbow. (Silver nitrate goes through a chemical reaction when exposed to light) Ritter discovered the reactions of the paper varied depending on the color that was shined on it.
Ritter wanted to continue his experiment. When exposed to violet light, the paper would turn much darker than any of the other colors. Then he tested for a "darker light" at the end of the color spectrum. When he did this, the paper turned even darker than when it had been exposed to violet light, proving that there was light beyond violet. This invisible light was named ultraviolet.
That's called the electromagnetic spectrum.
what does an electromagnetic spectrum consist of
the energy that makes the electromagnetic spectrum is electromagnetic radiation
Electromagnetic spectrum have different electromagnetic waves classified orderly according to their wavelength or frequency.
It lies in infrared region of electromagnetic spectrum.
The visible spectrum is a tiny, almost negligible slice of the electromagnetic spectrum. 'Sonar' has no place in this discussion. It's not even electromagnetic.
The electromagnetic spectrum includes electromagnetic waves with a continuous flow of the wavelength.
There are seven types of electromagnetic waves and they are: 1. Radio waves 2. Microwaves 3. Infra-red waves 4. (visible) Light waves 5. Ultra-violet waves 6. X-ray waves 7. Gamma rays
in electromagnetic spectrum visible light is safe for humans
Electromagnetic spectrum is a diagram that show the range, or spectrum of electromagnetic waves, in order of wavelength, frequency and energy.
Visible light is a small section in the electromagnetic spectrum.
No, The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.[1] The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.
