Demonstrating Ray DiagramsIn this post, we demonstrate ray diagrams using an arrayof arrows drawn on the board as the object and the camera on your phone as the screen.(i) Convex Lens : Arrows on the board are placed inside the focal length of the lens -> Magnfied Erect image(ii) Convex Lens : Arrows on the board are placed outside the focal length of the lens -> Inverted image(iii) Concave Lens: Irrespective of whether you place the arrows inside or outside the focal length, you get an erect image.(iv) Convex Mirror(v) Concave Mirror EDIT: Edited post to include concave and convex mirrors -- source link
