题型:单项选择题 A1/A2型题

题目:

Rayleigh散射是指()

A.当颗粒直径大于入射光波长的1/10时,散射光强度在各个方向的分布均匀一致

B.当颗粒直径小于入射光波长的1/10时,散射光强度在各个方向的分布均匀一致

C.当颗粒直径大于入射光波长的1/10到接近入射光波长时,随着颗粒直径增大,向前散射光强于向后散射光

D.当颗粒直径小于入射光波长的1/10到接近入射光波长时,随着颗粒直径增大,向前散射光强于向后散射光

E.当颗粒直径大于或等于入射光波长时,随着颗粒直径增大,向前散射光远远大于向后散射光

答案:

参考答案:B

解析:当颗粒直径小于入射光波长的1/10时,散射光强度在各个方向的分布均匀一致,称为Ray-leigh散射;当颗粒直径大于入射光波长的1/10到接近入射光波长时,随着颗粒直径增大,向前散射光强于向后散射光,称为Debye散射;当颗粒直径大于或等于入射光波长时,随着颗粒直径增大,向前散射光远远大于向后散射光,称为Mile散射。
