Drawing Ray Diagrams ♥ 6:09 pm

In the recent CTs, many of us had problems with that one Vain Jane mirror question, because we couldn't draw ray diagrams really well. So, let's take a look at the basics of ray-diagram-drawing.



Here's a sort of "cheat" that allows us to construct a ray diagram quickly, without using a protractor.



The second part of the above video shows a more complicated ray diagram:



Concave mirrors are mirrors that curve inwards. Let's find out more on how to draw ray diagrams for concave mirrors:



On the other hand, convex mirrors are essentially the opposite of concave mirrors, i.e. they curve outwards. Shown below is a video on how to draw ray diagrams for convex mirrors:



I hope that after watching these videos, drawing ray diagrams would be much simplier and clearer for us all! :D
