Introduction: Dispersion is the splitting up of white light into seven colors on passing through a transparent medium like a glass prism. When a white light beam is passed through a prism, a band of seven colors are formed is known as spectrum of white light. The seven colors in the spectrum are red, orange,

Introduction We can identify different quadrilaterals based on the properties sides, diagonals and angles. Quadrilaterals are made up of ten parts. However, to construct them, you do not need to know the measurements of all of them. In case of special quadrilaterals, like the rectangle, just two measurements, the lengths of its adjacent sides are enough to construct it. A kite can

Introduction When we dip three tubes with fine bores but with different diameters into a clean water, we observe that water rises in the tubes but the narrower the bore the higher the height to which the rises. Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of a liquid to flow in

Topic: FACTORIZATION: COMMON FACTORS a(b + c) = ab + ac The reverse process, ab + ac = a(b + c), is called taking out the common factor. Consider the factorisation of the expression 5x + 15. Clearly, 5x = 5 X x 15 = 3 X 5 ∴ HCF = 5 Thus 5x + 15 = 5 X x + 3 X 5 = 5(x + 3)
