Answer: Option (C) is correct
Explanation: Robert Hooke microscope is having a special facility as his microscope have Artificial lightening facility wich was not present in the microscope invented by Leeuwenhoek. Leeuwenhoek created a simple microscope having a single ball like lens which can visualize microbes which have magnification of about 270x-- 400x..

The first cell was discovered in 1665 by Robert Hooke, who observed non-living cells of cork using a crude microscope and noted that they looked like tiny "rooms in which a monk might live." Almost one decade later, Anton van Leeuwenhoek observed the first living cells, which he dubbed animalcules, meaning little animals. Scientists continued to use these early microscopes to observe cells for over a century, and repeatedly found the cell to be the discrete unit of life. These...

Some biological systems can act like an optical fiber. Below is a drawing which illustrates how this might occur. Imagine you have a long, thin cell surrounded by fluid with index of refraction 1.38. The average index of refraction inside the cell is 1.48. Compute the critical angle, theta_crit, for total internal reflection for this system. Show all of your computations. What will the angle of refraction be for ray A (shown below) that has an angle of incidence of...

If you drop a bar magnet down a tube made of conducting material (like copper or aluminum) something interesting happens: the bar magnet does not simply accelerate all the way down under the influence of gravity. Instead, there are forces that oppose the motion and cause the bar magnet to descend at essentially a constant velocity. Suppose you do this two times: once with the north pole of the magnet facing down and the second time with the north pole...
