Magna Carta Libertatum (Great Charter) a charter of rights agreed to by King John of England to make peace between the unpopular King and a group of rebel barons. First drafted by the Archbishop of Canterbury it promised the protection of church rights, protection for the barons from illegal imprisonment, admission to swift justice, and limitations on payments to the empire's Crown which was to be executed by council of 25 barons. Both sides breached their commitments, and the charter was invalided by Pope Innocent III, leading to the First Barons' War.
Section v: Lens and its uses
Lens is transperant material
that bends light in some pattern/ optical device
that focuses or disperses a light beam
 |
A lens is biconvex (double concave /
just concave) if both surfaces are concave
|
A lens is plano-concave if one surface
is concave and other is flat.
|
|
A lens is convex-concave or meniscus if one
surface is convex and other is concave side.
|
A lens is plano-convex if one surface
is convex and other is flat.

Non - Luminous objects
reflect light from luminous objects and travel to our eyes. The reflected light
gets reflected by mirror and reaches our eye and we see the object on the
mirror.
Uses of lens:
1) Telescope is an optical instrument for seeing distant
objects. In 1608, Galileo built the first telescope to observe the satellites
of Jupiter. Telescopes are of two types a) astronomical telescopes (for viewing
distance stars).Final image in the astronomical
telescope is inverted.
Terrestrial telescopes (for viewing distant objects on the earth). The final image is erect
2) Spectacles: Light enters eye thorugh the pupil. On the back
of the pupil lies the retina. The retina (at the rear of the eyeball) is a layer of sensitive nerves . Rays on the retina is deciphered into an image by the
brain. Eye lenses which do not focus light properly on the retina lead to vision
problems a) nearsightedness where focusses rays of light in front of the retina.
Concave lens can rectify the problem.
b) farsightedness where focuses
rays behind the retina. convex lens can rectify the problem
3) magnifying glass. Object placed within a focal length of
a converging lens, the lens produces a magnified image.
4) microscopes use lens systems to magnify very small
objects.
6) Solar Heating
