Calling all physics geniuses! An object is placed 20cm in front of a convex lens whose focal length is 12cm. What type of image is formed? Super helpful if you could answer in terms of inverted/upright/magnified/diminished/real/virtual.

1/v + 1/u = 1/f

1/12 - 1/20 = 1/f

5-3/60 =1/f

2/60 = 1/f

1/30 = 1/f

f= 30

This was done by mirror formula

Hope you understood
