Is V positive for concave lens?

And for image distance, V in lens it is taken as positive in Convex lens since image is formed on +X side. It is taken as negative in Concave lens since image is formed in -X side of the Cartesian. In Concave mirror V is taken as positive and negative for convex mirror.

Is V negative or positive in concave mirror?

If the image is formed behind a concave mirror, the image distance (v) is positive but if the image is formed in front of the mirror , then the image distance will be negative.

What is the sign of V for concave lens?

For a concave mirror, it depends for all other cases except when the object is between focus and pole where it forms a virtual, erect image sign of v is negative. For: object between focus and pole, v is positive. else, v is negative.

What is the V in convex lens?

v is denoted as the distance of the image from the optical center. In convex lens, the focal length is positive.

Is V negative in concave lens?

In case of a concave lens ‘v’ is always negative. In case of convex lens it is negative or positive it depends on object distance n location.

Is V positive for convex lens?

And for image distance, V in lens it is taken as positive in Convex lens since image is formed on +X side. It is taken as negative in Concave lens since image is formed in -X side of the Cartesian. In Concave mirror V is taken as positive and negative for convex mirror.

Is V negative in convex mirror?

‘v’ is always positive for convex mirror & concave lens. Distances measured from the optic center to the right of the lens are considered +ve and t from optic center to the left are -ve.

What is V in case of concave mirror?

f is the focal length of a concave mirror. u is the distance of object needle from the pole of the mirror. v is the distance of image needle from the pole of the mirror.

What is U and V in lens?

where u is the distance of the object from the lens; v is the distance of the image from the lens and f is the focal length, i.e., the distance of the focus from the lens.

How do you know if an image is positive or negative?

When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright. A negative m means that the image is inverted. Positive means an upright image.
