The Strangeness (1985)
Experiment: Determination of Focal Length of a) Convex Lens b) Concave Mirror by Obtaining the Image of a Distant Object
Focal length of a convex lens & Concave Mirror: a). Focal length of a convex lens: Objective: To determine the focal length of a convex lens using a distant object (like a sun, tree or tall faraway building). Principle: A convex lens converges parallel rays of light (from a distant object) to a point called principal focus (F). The distance between the optic centre (O) of the lens and the…
Experiment: To Determine the Focal Length of a Convex lens by Plotting Graphs Between u and v and 1/u and 1/v
Focal length of a convex lens: Objective To find the focal length of a convex lens using the lens formula by plotting u and v graph 1/u and 1/v graph Focal length of a convex lens: Apparatus and Material Required Convex lens (let’s assume f=10 cm) Optical bench with 3 uprights (with clamps) Optic needles Meter scale Spirit level Focal length of a convex lens: Ray Diagram Focal length of a convex…
Image formation by thin lenses
If the foot of the object crosses the principal axis, two of the three rays used to locate image should be drawn for both the tip and the foot of the object.
In books, we use ray diagrams to represent images formed by thin lenses. Ray diagrams are straight lines with arrows that shows direction of light rays. Points to note when drawing ray diagrams Real rays and real images are drawn using solid lines virtual rays and virtual images are drawn in broken lines To locate the image, two of the three important rays are drawn from the tip of the…

So, we’ve been learning in school about how our eyes have convex lens. We’ve also learnt how convex lens produce a real, small image of distant objects...
What if the reason far away objects appear smaller is cause we look at them through convex lens? So, maybe just swap out your convex lens for some concave, and viola! A different world! Maybe, a world where we cant look at all, cause then the sun would appear real big, idk
Difference between Concave and Convex Lens -The lens which is thinner in the middle than at the edges is called a concave lens.A concave lens is a spherical
