accommodation of the eye? Ans. The ability of the eye lens to adjust its focal length‚ so as to clearly focus rays coming from distant as well a near objects on the retina‚ is called the power of accommodation of the eye. Q2. A person with a myopic eye cannot see objects beyond 1.2 m distinctly. What should be the type of the corrective lens used to restore proper vision? Ans. A person with a myopic eye should use a concave lens of focal length 1.2 m so as to restore proper vision

Chapter 14 Outline I. Refraction of Light A. Refraction is the bending of light at the boundary of two media. 1. It is caused by differences in the way light travels in the two media a) Light changes speed unequally. (1) One side of the light becomes slower/faster 2. If light is perpendicular to the new medium‚ light will not refract a) If the media have the same index of refraction‚ light will not refract B. Index of Refraction 1. How well light travels through a medium is measured by

A ground breaking new tool used to study the heavens was introduced in the 17th century. This tool was known as the telescope. It revealed the cosmos in a different way than our naked eye could ever perceive. The telescope opened doors to countless stars‚ nebulae‚ galaxies‚ and a slew of never before seen wonders. With its creation came limitations and caused the need to improve and upgrade the methods in which the telescope functioned and find new ways of viewing the heavens.There are three main

Make sure there are no air bubbles. 7. Make sure the lowest power lens (the shortest lens) is in place over the stage. Place the slide onto the stage of the microscope. 8. Look through the eyepiece and turn the coarse focus knob (the largest knob) until an image comes into focus. It should look like scattered blobs. Move the slide

to allow more or less light. It is typically a plastic disk located between the light source and the specimen mount. The compound microscope has two systems of lenses for greater magnification‚ 1) the ocular or eyepiece lens that one looks into and 2) the objective lens‚ or the lens closest to the object. A microscope works by using lights‚ mirrors‚ and glass to magnify. The mirrors and glass bend the light in a certain way that it makes small objects appear larger. Method Procedure 1.2 Handling

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. Where do you place the slide on the microscope? the stage under the stage clips 4. Which adjustment‚ course or fine‚ do you use when you are observing the

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
