what is the electro-magnetic spectrum?

Answer 1

Electromagentic spectrum refers to light - all light, from 0 m to Mm wavelengths.

Electromagentic is named that way because light is the result of a oscillating magnetic field perpedicular to an oscillating magnetic field.

The visible spectrum of light is only a small subset of the electromagnetic spectrum which is approximately 400-700nm in wavelength.

Answer 2

The electromagnetic spectrum covers a wide range of wavelengths and photon energies. Light used to "see" an object must have a wavelength about the same size as or smaller than the object. The ALS generates light in the far ultraviolet and soft x-ray regions, which span the wavelengths suited to studying molecules and atoms.

Answer 4

The entire range of radiation extending in frequency from approximately 1023 hertz to 0 hertz or, in corresponding wavelengths, from 10-13 centimeter to infinity and including, in order of decreasing frequency, cosmic-ray photons, gamma rays, x-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves.

Answer 5

Hi. It is the range of frequencies that photons can vibrate at. From very short gamma rays to very long radio waves.

Answer 6

There are basically rather 3 hues. 3 usual hues it rather is. (pink, yellow & blue) each and each of something are secondary hues or a mixture of fairly some them. you probable already understand all this yet besides. I reckon that indigo is seen a color via fact they couldnt think of of yet another to flesh out the scene abit. rather there could basically be 3......

Answer 7

Radiowaves,microwaves,infra red,visible light,ultra violet,x rays,
gamma rays (and cosmic rays). from lowest to highest frequency.
These all travel at the speed of light.

Answer 8

it shows all the different forms of lightwaves existing......from micro waves to gamma rays.......

it is like showing all the colours on a lader...from the lightest to the darkest.......
