Physics : Light 12

Hello, everyone who likes physics🪫📡⚙️ This episode we share some questions to you to make our logic more clear. The final question, we talk about the two mirrors combined at 90° and 60°, then discuss the angle among incident light and reflect light. Actually when the mirrors’ angles are still 90° and 60°, we can discover the angle among incident light and reflect light are 2 times as 90° and 60° coincidentally. But when the angle of mirrors is 30°, and the angle among incident light and reflect light will be different (you can try to draw and calculate it or next time we do it together.) ▶️The solving is without a teacher, if here is anywhere inappropriate, I have to say sorry.◀️ The reflection law of light shows that light will change the direction of propagation at the junction of the medium, which is mainly composed of two core principles: 1.Co-faced, 2.Equiangularity.
