if it is not polished the rays pass through the mirror. The moisture from the mirror will start to create the black spots on the mirror. When the mirror is properly adjusted, light from behind reflects from the silvered surface into the driver's eyes. Clean the mirror face by spraying glass cleaner on an old towel or T-shirt and then wiping the glass. Bill Otto A factory for manufacturing mirrors called Saint-Gobain was established in France, but mirrors were still expensive luxuries and only the very rich owned it. However, precision optical surfaces normally need the reflective material on the front surface of the glass to avoid introducing optical abberations. Typically, a mirror is made by coating a thin layer of aluminum or silver on the back of a piece of smooth glass. so silvering helps the rays to reflect properly. hope it helps uu frnd dramaqueen22 dramaqueen22 Hello The exposed glass helps protect the mirror coating underneath from scratching or degradation due to environmental factors such as weather, fingerprints, and dust. Palomar, California. Why are mirror silvered at the back surface? Answer 4.8 /5 11 sonabrainly one surface of the mirror is silvered because it helps the light rays to reflect. Water is the enemy of mirrors. These mirrors use glass as a protective surface and have the mirror coating, commonly referred to as "silvering", on the back side, or "second surface". Class 12 Class 11 Class 10 Class 9 Class 8 Class 7 Class 6 so silvering helps the rays to reflect properly. Car mirrors are uncoated on the front surface and silvered on the back surface. Hi, I am Anchit a computer science engineer, as you know that light can travel so light can pass through transparent surface and to make an image of anything light is needed in real so to make image silver is polished to another side of the glass so that the light should not pass but to block the . Silvering is the chemical process of coating glass with a reflective substance.mirrors are back silvered, since this protects the fragile reflective layer from corrosion, scratches, and other damage. A plane glass mirror of thickness 3 c m of material of = 3 / 2 is silvered on the back surface. 9 . The integrity of the silver depends on the integrity of the backing paint. A protective layer of paint is usually applied to protect the back side of the reflective surface . Which surface of concave mirror is polished? Metals are the most commonly used mirror coatings. We recommend using ammonia free alcohol window cleaner or even lens cleaner. if it is not polished the rays pass through the mirror. [1] Household mirrors are coated on the back while mirrors used in optical applications feature front-surface mirrors. Why are mirrors not transparent even though they are made of glass?

But this is not so good at nighttime with the glare of headlights behind. When the mirror is properly adjusted, light from behind reflects from the silvered surface into the driver's eyes. In 1835 Justus von Liebig, a German chemist, developed the silvered-glass mirror where a thin layer of metallic silver is put onto glass by the chemical reduction of silver nitrate. This problem is solved by the wedge shape of the mirror (see sketch). if it is not polished the rays pass through the mirror. Because of their reflectivity, layers of aluminum and silver are often used. Most common household mirrors are "back-silvered" or "second-surface", meaning that the light reaches the reflective layer after passing through the glass. Suction and friction can loosen the backing paint and expose the silver to further corrosion. Good. The back of a common flat mirror is silvered for convenience and durabilty. Car mirrors are uncoated on the front surface and silvered on the back surface. This problem is solved by the wedge shape of the mirror (see the sketch). This is found in applications where unwanted refraction is not desirable. Small cracks can be cured with a glass repair kit. Why mirrors are silvered on the back surface? Good. A. Silver is the most reflective across the visible spectrum, reflecting 95 percent of light. Why Do Mirrors Desilver? This means that the reflective surface--in most modern mirrors this is aluminum--is viewed through a thin layer of glass. There are a few cases, where the silvering is on the front surface. The type of inexpensive mirror used in bathrooms or car side mirrors do not require a precise surface for its particular application. so silvering helps the rays to reflect properly. The surface often gets wet with condensation or dusty so that a durable first surface is required such as glass. An example of this is seen in the mirror of the 200 inch reflecting telescope at Mt.
