    Content.  Introduction.  Parts of light microscope.  Steps to setup light microscope.  Uses of light microscope.  How to clean light microscope.  Maintain the light microscope.  Summery.  References. Introduction. Light microscope is an instrument which used to magnify small specimen which cannot be seen through naked eye, by using a light source. It helps to magnify the small object to 1000* times than the real size of the real object. In light microscope light ray is send and it travel as a beam through the specimen and then through the lenses finally producing a magnified image. But this mage is inverted. If it’s necessary to erect we have to use another extra lens. To get a clear image we have to use a thin specimen which allows light beam to travel through it.…

    Dispersion Of Light Essay

    • 904 Words
    • 4 Pages

    2.4.3. Dispersion of Light The fact that the refractive index different for each wavelength of light produces an effect called dispersion. This can be seen by shining a beam of white light into a triangular prism of glass. White light entering a prism is refracted in the prism at different angles depending on the wavelength of light. The refractive index for the longer wavelengths (red) is lower than for the shorter wavelength (violet). This leads to a large angle of refraction for the longer…

    Lab Question: Does the intensity of light affect the plant’s photosynthesis? Background information: There are three main elements which has a huge impact on the plant’s photosynthesis: light, temperature, and carbon dioxide.(Plant and Light) However, this lab is focused on how the intensity of light affect the plant’s photosynthesis in order to see how the intensity of light affect the plant’s photosynthesis, specifically Elodea plants. Photosynthesis is a process which happens in all plants…

    Evolution Of Light Waves

    the object, its wavelength shifts as the object moves (this is known as the Doppler effect). The radar detects the shift and calculates how fast the object is traveling, along with it's location. 2. Polarized sunglasses block reflected light (glare). Since polarized light waves travel in a generally horizontal direction, the glasses have a special filter to block out this specific kind of wavelength, so only nonpolarized light can pass through! 3. When we see a rainbow, it is the result of the…

    Color Light Observation

    • 1354 Words
    • 6 Pages

    Observation Why do shadows form? Why does light change directions when it hits a mirror? Why can't you see sun rays in the atmosphere? Why does a sun ray turn into a rainbow when going through a prism? Why do mirages happen? Why does an object's appearance (color) change when in different color light? How do a bunch of tiny colored lights in a television make up just one color? Why in water, does it look like a straw is bent but it really isn't? What happens to a piece…

    Light Color and Photosynthesis Rate Introduction: How do the wavelength of visible light affect photosynthesis? Photosynthesis, a process used by plants and other organisms to convert light energy into chemical energy that can be released later to fuel the organisms’ activities, depends upon the absorption of light by pigments found in the plant leaves. Pigments, such as chlorophyll and carotenoids, absorb and reflect light based on the wavelength of light. To be more explicit, photosynthesis…

    Light Wavelength Essay

    • 1065 Words
    • 5 Pages

    When we think about light we think something that is visible to us. For example, the light that comes from a light bulb or your car headlights and the sun. But in fact, we are recognizing “white lights.” This is the light that is divided up into six elementary colors; red, orange, yellow, green, blue violet. This is true when you place a thick piece of glass in the sunlight and a rainbow band of colors appear. These colors are put onto a light spectrum with its shortest wavelength are violet…

    Light In Romeo And Juliet

    John Steinbeck once quoted, “It’s so much darker when a light goes out than it would have been if it had never shone.” In decree to appreciate something for all that it really is, one must learn to collate it to its opposite. These opposites both bring out the worst in each other in addition to complementing each other. Moreover, they also bring out the energy through the tension in which they take. Simultaneously, this is true in literature everywhere. Authors often make use of opposition, thus…

    Light In Neon Signs

    • 255 Words
    • 2 Pages

    The light in neon signs are made of neon gas placed into glass tubes bent into decorative designs. Neon is used very often because it as a noble gas. This is because the every atom has an electron shell, therefore the atoms do not react with other atoms and it becomes very difficult to remove an electron because it would take much energy. When a high-voltage electrical current passes through the neon gas, its energy can remove an electron. The atoms in the tube are moving around and hitting…

    • 4 Pages

    Physics: Analogy of Light and Sound Light and sound share many common aspects. Today, we will study some of notable similarities and differences between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the…
