Chemistry in our daily life

Plants cannot grow in too alkaline or too acidic soils. Therefore, for proper cultivation of crops it is important to have knowledge of the pH of the soil. If the soil is too acidic then its pH can be raised by adding lime or slaked lime which neutralizes the excess acid in the soil.

May 14, Uses of concave mirror The concave mirror is a converging mirrorso that it is used for many purposesIt is used as a torch to reflect the lightIt is used in the aircraft landing at the airports to guide the aeroplanesIt is used in shaving to get an enlarged and erect image of the face.

The concave mirror is used in front lights of cars to reflect the lightIt is used in marine lighthouses that are found at the marine ports and at the airports to guide the ships and it is used in the solar ovens. The concave mirror is used in the solar ovens and the solar furnaces to collect a large amount of solar energy in the focus of the mirror for cooking foodheating waterrecharging power backups or melting metals respectively.

Concave mirrors are used in satellite dishesThey are used in telescopesDentist and ENT doctors use them to obtain a larger image than the Chemistry in our daily life of the teethear or skin etc. Concave mirrors are used in the electron microscopes and magnifying glassesThey are used in the visual bomb detectors and they are used in the flash light mirror of camera.

Real image and Virtual image Concave mirror and the convex mirror The real image is formed as a result of the intersection of the reflected light raysIt can be received on a screen and it is always inverted. The focus of concave mirror The focus of the concave mirror is produced due to the collection of the reflected rays emitted from a far object such as the sunThe rays after being reflected collect in one lit point which is called the focus of the mirror that can be received on the screen.

When the incident light ray parallel to the principal axisIt reflects passing through the focusWhen the incident light ray that passes through the focusIt reflects parallel to the principal axisWhen the incident light ray that passes through the center of curvatureIt reflects back on itself.

Cases of formation of the images by the concave mirror When the position of the object is very farthe position of the image is at the focusThe image is real and very tiny dot.

The object is at a distance greater than the radius of curvature after the center of curvatureThe image is at a distance greater than the focal length but less than the double of focal length between the focus and the curvatureThe image is realinverted and diminished small.

When the object is at the center of curvature at a distance equals the radius of curvatureThe image will be at the curvature centerThe image will realinverted and equal to the object. When the object is between the center of curvature and the focus at a distance more than the focal length but less than the radius of curvatureThe image is after the center of curvature at a distance greater than the radius of curvatureThe image is realinverted and enlarged magnified.

When the object is between the focus and the pole at a distance less than the focal lengthThe image is behind the mirrorThe image is virtualupright erect and magnified. When the object is at the focusNo image is formedThe image is at infinity where the rays penetrate as parallel.

The convex mirror is suitable for convenient shop and big supermarket and any other corner where need anti-thiefIt is used in the turning off the road and parking.

Convex mirrors are used inside the buildingsThey are also used in making lenses of sunglassesThey are used in magnifying glassThey are used in securities and they are used in telescopes. They can be used as street light reflectors because they can spread the light over a bigger areaThey are put on the corners of roads so that you can see any cars coming to avoid the collisions and they are used as ceiling dome mirrors.

Properties of the formed image by the convex mirror Wherever the position of the object in front of the convex mirrorthe image is smaller than the objectIt is upright erectIt is virtual not received on a screen.Life Out of Balance: Smartphones et al.
