why is 'u' or distance of object negitive?
Asked by | 10th Mar, 2008, 06:51: PM
As per the new cartesian sign convention,the object is always placed to the left of the mirror/lens and all the distances measured to the left of the origin (along - x axis) are taken as negative. Hence, the numerical value of u is taken as negative.
