The little one is the radio waves
and hardlest is gamma rays.

  1. RADIO WAVES:radio waves are the longest waves of  the electromagnetic spectrum, broadcast stations use them to carry signals in a kind of code AM or FM.



2.MICROWAVES:microwaves are shortwave radio waves.microwave ovens can heat many  foods faster , using less enrgy tha a regular oven.










3.INFRARED LIGHT:infrared light means "just beyond red ." All objects give off more infrared waves , depending on their temperature.










4.ULTRAVIOLET LIGHT:ultraviolet(UV)light is made up of waves just shorter than visible  violet light  on the spectrum.






5.X RAYS: x rays can pass right through most objects.Thicker or denser objects tend  to absorb x rays.









6.GAMMA RAYS: the shortest wavelengths of the spectrum-gamma rays.
