反射定律和平面鏡形成的像有甚麼關係?
我知的反射定律是:
1.法線 入射線 反射線 都在同一平面上
2.入射角=反射角
我知平面鏡形成的像有以下特性:
1.橫向倒置的
2.正立的
3.和物體大小一樣的
4,物距=像距

✔ 最佳答案
The Law of Reflection actually determines the nature of image formed by a plane surface.
The equality of the incident and reflected angles, together with the plane surface, form a series of congruent triangles. From geometry, corresponding sides of two congruent triangles are of equal lengths, this gives the specified nature of image formed by reflection on a plane surface.
