light
wavelenght - 400 to 700
frequency - 750 to 420 terahertz
terahertz = 1 trillion hertz
in terms of visibility light is divided into 3
-->infrared
--> visible light
-->ultraviolet
infrared- long wavelenght
less frequency
ultraviolet- short wavelenght
high frequency
properties of light -->intensity
-->propagation of direction
-->frrequency/wavelenght
light and photon
light is packets of energy or light is packed photons
photon
--> charge = 0
--> spin - 1 (clockwise or anti-clockwise)
-->rest mass = 0
--> 'c' or speed = 299.792,458m/s
