For light rays travelling from a fabric with a higher index of refraction to a fabric with a reduced index of refraction, Snell's regulation predicts that there's no θ2 when θ1 is large. In this case, no transmission takes place; every one of the light is mirrored.Weather radar – A Doppler radar which maps weather conditions precipitation inten
