I'm having a lot of trouble drawing ray diagrams (this is for a lab assignment). If anyone could give me some tips or links to websites that are helpful in teaching how to draw ray diagrams that would be great. One example of a problem is: A 1-cm tall arrow (the object) is placed 2 cm to the left of a converging lens having a 7 cm focal length. Show all three pricipal rays. Is the image real/virtual?Erect of inverted? Measuring from diagram determine the location and magnification of the image.
Now I think that I draw an upright arrow, 1 cm tall, to the left of the lens and then 7 cm to the right of the lens i draw another arrow? Is it upside down, larger/smaller? I have no idea what I'm doing and the write up for the lab is not helpful. Please help! thanks
