激光係咪偏振左?

激光無論係相干性/方向性/亮度/單色性, 都非常高.
原因係每一個原子入面, 電子振動既頻率幾乎完全相同.
咁激光係咪偏振光?

希望你地解答到我啦, 吾該哂=]

To pc7086: I think you better delete your answer because I wont accept it. laser is a monochromatic light, CANNOT deduce that it a polarized light.

the EM Wave and the sun light emit the light(energy) in ALL DIRECTION,
if you want to group them into one direction,you have to use polaroid to make the waves polarized.

laser is a monochromatic,so it a polarized light.
