Homework Statement
An object is locted 15cm infront of a convae lends with a focal length of 10cm. use ray tracing to determine the location of the image. try to draw to scale
i)is the image upright or inverted?
ii)is the image real or virtual?
iii)use your ray-tracing diagram to determine the distance from the lens to the image and label your diagram with this value
iv)now calculate this lens to image distance using the thing lens formula
v) determine the linear magnification of the image relative to the object
Homework Equations
1/p+1/q=1/f
m=-q/p
The Attempt at a Solution
the image will be upright and virtual. and i was able to do the ray tracing diagram
for part iii) I am unsure which equation to use as if i use the lens formula i get the wrong answer,
1/15+1/q=1/10
and hense the wrong answer for part iv)
i'm able to work out v if i have the answer for iv. as m=-q/p which will be m=-answer/15
