album1(invisible light)


Invisible light are the the type of light that we can don't see,touch or hear.

  • Radio waves:are the longest wave electromagnetic spectrum.Have 2 stations use them to carry signals in code that are AM and FM.They also carry signals for your television and cellular phones.










  • Microwaves:are shortwave radiowaves.Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke.











  • infared light:Infared waves are next to visible red waves in the spectrum. Is part of the electromagnetic wave spectrum that borders the lowest frequency longest wavelength among those that make up visible light.













  • ultraviolet light:Ultraviolet  light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects, like bumblebees, can see them. 













  • x rays:X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves.x rays can pass right throught most objects.











  • gamma rays:Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells.
