background ( 3). It has two lenses the objective and the ocular and they create the image by working together. Light pass through the specimen by a light source which is located on the base and is focused by the objective lens which can magnify from 4 to 100 times‚ then the ocular lens further magnifies the image by 10 times. The total magnification is calculated by multiplying the objective and the eyepiece magnification together (3). When a ray of light passes from one medium to another‚ refraction

What is the difference between the ocular lens and the objective lens? Ocular lens is the lens you look through and objective lens is the lens that is close to the stage. 3.

The microscope lenses should clean with a lens cleaner solution and a lens paper due to possible minerals or deposits on the any soft tissue. | | 2) The coarse adjustment knob maybe used in focusing with all objective lenses.False.

1) The condenser lens concentrates light and makes illumination of image more uniform. 2) The bending of light is also known as refraction. 3) Total magnification = ocular lens magnification x objective lens magnification. 4) The total magnification of an image is 1200x and the magnification of the ocular lens is 10x. What is the magnification of the objective lens? Y = objective lens 1200x = 10x X y 1200x / 10x = y y = 120x Objective lens magnification = 120x 5) The limit of resolution

CHAPTER – 10 LIGHT-REFLECTION & REFRACTION Light is a form of energy‚ which enable us to see the object. In this chapter we will study the phenomena of reflection and refraction using the property of light i.e. straight line propagation (Light wave travel from one point to another‚ along a straight line). Reflection of Light When the light is allowed to fall on highly polished surface‚ such as mirror‚ most of the light gets reflected. normal Laws of Reflection 1. 2. The angle

The ocular micrometer has no units. 5. Objective lens The objective lens gathers light from the specimen‚ magnifies the image of the specimen‚ and projects the magnified image into the body tube. Since no single objective lens can fulfill all the needs of someone using the microscope‚ several objective
