Which illustration shows the correct path of light through a lens? asap

Option D

Explanation:

A lens is an optic device that can be used for the refraction, converging or diverging rays, of light. The two major types are the converging and diverging lenses. Each lens is bifocal which implies that it has two sides, and can be splitted into meniscuses.

A converging lens is thicker in the middle and thinner at the edge. It converges all rays of light propagating through it parallel to its plane to a point.

A diverging lens is thinner in the middle but thicker at the edge. It is diverges all rays of light propagating through it parallel to is plane as if they originate from a point.

Considering the given diagrams, option D depicts appropriate path of light through a lens. The arrows shows the rays of light and directions of their propagation.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
