2) broad spectrum of light(variety of wavelength)
3) puts out light in every direction at the same time
4)more safety compare to laser]]> 2018-09-23 07:10:41 UTC https://padlet.com/norainh/LASER2/wish/284704081 Why we cant use normal light for surgery (weaknesses) https://padlet.com/norainh/LASER2/wish/284791115 1) Because normal light has poly-chromatic light that contains light with more than one wavelength 
2) low directionality (broad width)]]> 2018-09-23 19:35:55 UTC https://padlet.com/norainh/LASER2/wish/284791115 Why cannot use laser as a street light? https://padlet.com/norainh/LASER2/wish/284869996 1. Divergence of light is less
2. High power and focus radiation]]> 2018-09-24 06:52:23 UTC https://padlet.com/norainh/LASER2/wish/284869996
