Question

The term microscope was coined by
(a)Janssens
(b)Faber
(c)Hooke
(d)Leeuwenhoek

Answer 1

He was a German ecclesiastical specialist, botanist, and craftsmanship gatherer, initially from Bamberg in Bavaria, who lived in Rome from 1598.
He was a curator of the Vatican arboretum, a member and therefore the secretary of the Accademia dei Lincei. He acted all through his profession as a political intermediary between Maximilian I, Elector of Bavaria, and Rome.

Complete answer:
The term microscope was coined by Faber. It was mainly used for the compound microscope. It was termed as the little eye by Galileo. It has a magnifying lens which helps to accentuate the size of the microscopic objects. It has two sets of lens objectives and eyepiece which helps in magnification. The number of times it magnifies is understood as magnification power.

Additional Information: Microscopes can be separated into several different classes. One gathering is predicated on what collaborates with the example to get the picture, i.e., light or photons (optical magnifying instruments), electrons (electron magnifying instruments), or an inquiry (scanning magnifying instruments). Then again, magnifying lenses are frequently arranged upheld whether they or not investigate the sample by means of a scanning point (confocal optical magnifying lens, scanning electron magnifying lens, and scanning probe magnifying instruments) or dissect the sample all legitimately (wide-field optical magnifying instruments and transmission electron magnifying lens).
Widefield optical magnifying instruments and transmission electron magnifying lenses both utilize the possibility of focal points (optics for light magnifying instruments and electromagnet focal points for electron magnifying lens) to amplify the picture produced by the section of a wave transmitted through the sample, or reflected by the example. The waves utilized are electromagnetic (in optical magnifying instruments) or electron radiates (in electron magnifying lens). Resolution in these microscopes is restricted by the wavelength of the radiation wont to image the sample, where shorter wavelengths leave a better resolution.
So the correct answer is ‘Faber’.

Note: The most common type of microscope (and the first invented) is the optical microscope. This is an instrument containing one or more lenses producing an enlarged image of a sample placed within the focal plane. Optical magnifying instruments have a refractive glass (every so often plastic or quartz), to shine a light on the consideration or on to an alternate light detector. Mirror-based optical microscopes operate in the same manner.
