Focal Length Of Convex Lens Experiment. Determinatiom of the diameter of a fine wire via interference phenomenon. There should not be any hurdle between the rays of light from the object and the convex lens.

An important property of a lens is its focal length. f. Focal length of the convex lens (by distance object method) is (f) =.………cm.

The lens maker’s equation for the focal length. f. of a lens is1 1 f =(n− 1) 1 r1 + 1 r2. In an experiment a convex lens of focal length 1 5 c m is placed coaxially on an optical bench in front of a convex mirror at a distance of 5 c m from it.

The distance between the optical centers to the principal focus of a lens is called focal length of that lens and it is expressed by ƒ. Two convex lenses of different focal length and an optical bench with four uprights;

Measure the distance between the screen and the lens (v). This property is the reversibility property of thin lenses.

The convex lens is mounted in thev groove of the lens stand with its principal axis horizontally.the lens is focussed towards a distant object like a tall tree(palm tree) or electrical pole through the window of the laboratory.the position of the screen is adjusted on the other side of the lens until a clear image is formed on ot.the distance. Focus the lens towards various distant objects and repeat the experiment to find the position of sharp image and thereby the focal length.

Repeat for a variety of object distances. ensuring that it is always greater than the approximate focal length. (1) because the surface of a lens may be either convex or concave. there.
U Is The Distance Of I From The Optical Centre Of The Lens L2;
So. the power of a lens is defined as the reciprocal of its focal length. The relation between the object distance u and the image distance v for a convex lens placed in air is. We can conclude the focal length of the convex lens which are 9.82cm (found by “lens formula method”. uncertainty is 0.15cm) and 9.76cm (found by “lens displacement method”. uncertainty is 0.06cm).
If The Focal Length Of A Lens Is Expressed In Meter And Sign Of Its.
It is found that an object and its image coincide. if the object is placed at a distance of 2 0 c m from the lens. For an object that is infinitely far away (d o!1). Measure the distance between the lens and the screen (image distance) using the metre stick.
Keep The Upright Fixed In This Position Throughout.
Focal length of convex lens experiment. The relation between u . v and for a convex lens is. Repeat the same procedure. by changing the distance of the object (u) and tabulate your observations.
To Verify The Expression For The Focal Length Of A Combination Of Two Lenses.
Comparing above equation with the standard equation of a straight line. y = mx + c. on plotting a graph. In an experiment a convex lens of focal length 1 5 c m is placed coaxially on an optical bench in front of a convex mirror at a distance of 5 c m from it. Simulator procedure (as performed through the online labs ):
