    Namee: Paul G. Zamora (Homework in Performance Techniques) Sound Waves- A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air‚ water‚ or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration‚ such as a ringing telephone‚ or a person’s vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them

    CPI (Consumer price index) A consumer price index (CPI) measures changes in the price level of consumer goods and services purchased by households. The CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. GDP deflator In economics‚ the GDP deflator (implicit price deflator for GDP) is a measure of the level of prices of all new‚ domestically produced‚ final goods and services in an economy. GDP stands for gross

    Index of refraction The index of refraction of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in the medium. [pic] By definition‚ n = 1 in vacuum. In all materials n > 1. The frequency of light does not change as it goes from one a medium of one index of refraction to another. This means that the wavelength changes with the speed. [pic] Thus‚ the wavelength is smaller in a medium than in vacuum. From the definition of the index of

    OVERVIEW INDEX NUMBERS compare figures which show changes in a given variable. The most common variables used in index numbers are price and quantity. By getting the difference of the index numbers‚ we are able to determine the relative or percent change in the price or quantity of a commodity between two periods of time or two localities. Among the more commonly used index numbers are the consumer price index‚ retail price index‚ wholesale price index‚ and the cost-of-living index. DEFINITION

    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
