Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Light microscopes
A
Are generally not used to view bacteria
B
Work by reflecting electrons off the surface of an object being studied
C
Typically provide more resolution than an electron microscope
D
Use light and glass lenses to magnify an image
Explanation: 

Detailed explanation-1: -The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective lenses to enlarge the image formed.

Detailed explanation-2: -The optical microscope, often referred to as the “light optical microscope, ” is a type of microscope that uses visible light and a system of lenses to magnify images of small samples. Optical microscopes are the oldest design of microscope and were possibly designed in their present compound form in the 17th century.

Detailed explanation-3: -A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.

Detailed explanation-4: -They have an objective lens (which sits close to the object) and an eyepiece lens (which sits closer to your eye). Both of these contribute to the magnification of the object.

Detailed explanation-5: -The light microscope. The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. The lens closest to the eye is called the ocular, while the lens closest to the object is called the objective.
