Hey there!
Can anyone tell me the easiest way of remembering Ray diagrams of Spherical mirrors & lenses.?
Acc. to your point of view, which are more important mirrors or lenses.?
Ch.-Light Class10 CBSE.

A very simple trick.... it's using the basics:
Where ever the light ray touches the mirror, draw a dotted line(or even a normal line from there towards the focus of the mirror....yes atleast you need to know where the focus, centre of curvature of the mirror and lens is.
Then the line that you've drawn, just extend it opposite (if it's a mirror). For lens, and more understanding refer the pic

All you need to do is make diagram with correct measurements. they would automatically get accurate.
CONCAVE MIRROR & CONVEX LENS
→from infinity image would be point sized
then it would progressively keep on increasing
till it reach focus. where it would form an image at infinity. when the object would be btw focus and pole it would be virtual in both cases (mirror & lens)
→ another point to remember is that. in case of mirror the image formed (behind or front) would be opposite to that of lens. so you need to remember just one. it's a pro tip
CONVEX MIRROR & CONCAVE LENS
→both of these would always form virtual images in any case. it the object is at infinity the image would be point sized & if it's btw infinity & pole then diminished.
hope it helps
