phrase in the blank to make the statement true. | 1) The microscope lens may be cleaned with any soft tissue.False. 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. The coarse adjustment knob should be used during scanning objective lens (lowest power). When it comes to higher objective lenses‚ the fine-focus

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

power and is used for all focusing when using high power lenses. 4. Ocular lens The ocular lens‚ or eyepiece‚ magnifies the image. It contains a measuring scale called and ocular micrometer. 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

270220141122 INTRODUCTION Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Objective The objective of learning about the limitation of sight and hearing: ● I have learnt that our hearing and sight has limitation. ● I have learnt that we can overcome the limitation of our sight and hearing by using or wearing technology devices. ● The technology devices have make our lives easier. Limitation Of Sight Our sense of sight has its limitations

One hand is placed under this when carrying the microscope. 7. Eyepiece - Contains a lens that magnifies about 10X. You look through this. 8. Fine Adjustment Knob - Moves the stage or body tube for focusing with the high-power objective lens. Focuses for details. 9. Course Adjustment Knob - Moves the body tube or stage for focusing with the low-power objective lens. 10. Objective Lens - Magnifies the object from 4X to 40X. 11. Stage Clips – Hold the slide in place on the stage

how to use a microscope and oil immersion lens while observing prepared bacterial slides and also to prepare slides for observable bacteria culture from yogart. Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides with 10x and 40x objctives lens. In each slide the differences was magnification
