my question is how do you determine the height of the image do you have to draw the ray diagram first to scale and then measure physically with a ruler or is there a way to mathematically do it
the formula for calculating magnification of an object is
M=hi/ho (magnification = height of image/height of object)
so here is a sample problem
a 1.5cm high object is 8.0 cm from a converging lens of focal length 2.5 cm
for this the object height is given its 1.5cm and the image height is -0.70cm how do you get that by drawing?
