Question

Which of the following is NOT necessarily a part of a school laboratory compound microscope?
1. Mirror
2. Objective lens
3. Eye-piece
4. Camera

Answer 1

Correct Answer - Option 4 : Camera

The correct answer is Camera.

• The camera is NOT necessarily a part of a school laboratory compound microscope.

• A camera is an optical instrument used to capture an image.
• At their most basic, cameras are sealed boxes with a small hole that allows light in to capture an image on a light-sensitive surface.
• Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. 
• The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce.
• Using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light.

• A mirror is an object that reflects an image.
  • The light that bounces off a mirror will show an image of whatever is in front of it.
  • When focused through the lens of the eye or a camera.
  • Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it.
• In microscopy, the objective lenses are the optical elements closest to the specimen.
  • The objective lens gathers light from the specimen, which is focused to produce the real image that is seen on the ocular lens.
  • Objective lenses are the most complex part of the microscope due to their multi-element design.
• An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.
  • It is so named because it is usually the lens that is closest to the eye when someone looks through the device.
