Can someone please be kind enough to explain this with the general webers formula : change in intensity = intensity x constant
- I understand how 10-12 is the JND = 2 JND, and then going from 10-20 is doubled, so must double the JND, but I would have never thought of this by just looking at the question. Does someone have a different way of understanding this problem?
