Biology – Chapter 1 Study Guide The goal of science is to try to understand the world around us. Scientists often work in groups so they can exchange data‚ which is extremely important in the study of science. Understanding of science and the scientific approach is essential to intelligent decision making because it would make scientists make reasonable decisions and conclusions. A control is the experiment set-up not containing any independent variable. Analyzing data and drawing

Reflecting Telescope Telescope A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century‚ using glass lenses. Today‚ the reflecting telescope is considered as one of the most powerful scientific instruments ever invented. Within a few decades‚ the reflecting telescope was invented‚ which used mirrors. In the 20th

pilocarpine (Fig. 5)‚ 0.45 mg. per kilogram of atropine was administered intraperitoneally. Nine minutes after the atropine‚ the myopia had increased and then remained high until a larger dose of atropine‚ 0.8 mg. per kilogram‚ was given. The pupil contracted maximally during the experiment‚ and dilated only after the second dose of atropine. The remarkable fluctuations in refraction after 50 mg. per kilogram pilocarpine (Fig. 5) were not due topilocarpine (Fig. 5)‚ 0.45 mg. per kilogram of

AIM : To find refractive index of any liquid (water) using a concave mirror. APPARATUS: A concave spherical mirror‚ water‚ an optical needle‚ a clamp stand‚ one meter scale‚ plumb line‚ etc. THEORY: If the tip of object needle 0 be at the centre of curvature C‚ tip of image will exactly coincide with it. (Principle axis is verticle to the plane). When water is filled in concave mirror‚ object needle is again replaced to move to C’ to remove parallax between tips of object needle and its image. A

types of cameras such as the typical lens‚ mirror‚ or even mirrorless. They are all used differently depending on what the photographer aims to capture or envisions for the shoot. I am going to be talking about mirrors and lenses in cameras‚ how they are used‚ what cameras they are in‚ and of course how they work. Firstly‚ lets talk about what a lens is. A lens is a transparent object‚ typically made of glass‚ with one or two curved surfaces. There are different lens like concave and convex‚ cameras

wavelength of light. Because the velocity of light in air is always greater than that through a liquid‚ the refractive index is a number greater than 1; for example‚ hexane n20D 1.3751. The superscript 20 indicates that the measurement was made at 20 oC‚ and the subscript D refers to the yellow D-line of a sodium vapor lamp‚ light with a wavelength of 589 nm. The measurement is made with a refractometer using a few drops of liquid. Compensation is made within the instrument for the fact that white
