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.

WebKey Takeaways. An impedance mismatch in a circuit or along a transmission line will produce a reflection back to the source of the signal. When a signal reflects, the power transferred downstream towards a load is reduced. Impedance matching provides a dual role of enabling power transfer into a load by suppressing reflections. イオンフィナンシャルサービス採用倍率http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/freseq.html イオンファントム色WebReflection and transmission of EM waves (PDF - 1.1MB) Reflection and transmission of EM waves (PPT - 17.7MB) 30.
