Does the value of ns (negative or positive) suggest whether the photo is digital upright or genuine inverted? Or am I just to know concave lens is diverging and also produces virtual upright and vice versa? say thanks to you
UV - Upright Virtual
IR - inverted Real
For lenses, a virtual picture is top top the very same side together the object. For mirrors, a virtual photo is the contrary the object.

For lenses, a real photo is ~ above the opposite side of the object. Because that mirrors, exact same side. You could likewise draw the end the beam diagrams, yet it bring away time and is error-prone.
Not rather sure what ns is supposed to represent. Also do you mean concave mirrors? or Converging lens?
A general rule of thumb is because that a converging lens, if the thing is ~ above the very same side together the incoming light source, the picture will it is in inverted, real and also on the various other side of the lens whereas for diverging, the picture will be on the same side together the object and also virtual.
For calculating orientation it's probably much better to usage m=-di/do wherein di is the image distance and do is the object distance family member to the mirror/lens. A + answer way it's upright and also - way it's inverted with respect come the object.
If f is +, the winter is converging; - the winter is diverging
If ns is +, the image is real; - the photo is virtual
Diverging winter will constantly produce digital upright images
Converging and also o f, actual inverted image
Convex mirror is divergent, concave lens is divergent
Concave winter is convergent, convex lens is convergent
Basically 'i' will be confident if the is where the light beam is actually going. Because that example, a lens refracts irradiate so the irradiate rays happen through. So, a confident 'i' is when the image is on the opposite side of the irradiate source.

In a mirror, light rays room reflected. Therefore a optimistic 'i' is when the photo is top top the exact same side as the irradiate source. Hope that renders sense!
