Is The Formula µ = Real Depth/ Apparent Depth Valid If Viewed From A Position Away From The Normal?

Question

Is the formula µ = Real depth/ Apparent depth valid if viewed from a position away from the normal?

Solution

No, if the line of vision is not normal, apparent depth will be different for different inclinations. So, the ratio of real depth and apparent depth will not be a constant.
