Ray diagram for a convex lens(steps, 1-5)
Question | Answer |
---|---|
1 | draw line (optical axis) through center of lens&label focal point that is on the opposite side of the lens as the object |
2 | draw ray parallel to optical axis from top of object to lens&then have it refract through focal point on right side of lens |
3 | draw 2nd ray from top of object passing through centre of lens, ray won't bend as it passes through lens |
4 | if rays converge on the right side of lens, where they cross will indicate the top of inverted image |
5 | if rays diverge on the right side of lens (happens when object is less than 1 focal length from lens), extend them back with dotted lines&where they cross will be top of image |
