This following applet is Intensity of reflected light and index of refraction

Original project Intensity of reflected light and index of refraction

For normal incident light from air to glass, only 4% light were reflected.
I=(n1-n2)2/(n1+n2)2=(1-1.5)2/(1+1.5)2=1/25=4%
The intensity of reflected light changed with index of refraction and the incident angle.
