"Web2. Electromagnetic radiation will reflect from any change in refractive index. For light reflecting off snow you have an air/ice boundary, and the refractive index of air is about 1.0 while ice is about 1.3, so you get reflection. Actually you get multiple reflections which is why you get a diffuse scattering and why ice looks white. " - Em waves reflection
