All about Mirrors

     It is glass-coated with metal amalgam which reflects a clear image. Mirrors are found in vehicles, the tools used by a dentist, changing rooms, and other places. 
There are three types of mirrors- convex mirrors which are used in vehicles, concave mirrors used by a dentist to examine teeth, and plane mirrors found in trial rooms or dressing tables.
     The image formed by a convex mirror is small and erect. This helps the vehicle's driver see a larger area and better idea the traffic or the other vehicles around. Also, the image formed is inverted. This is why in an ambulance the word 'AMBULANCE' is written backwards. When a driver views in the side or rear-view mirror, he/she will read the word correctly, hence giving way for it to pass. 

     A concave mirror on the other hand forms an enlarged image. Dentists use this mirror to examine the teeth properly and do the required treatment. 
Plane mirrors reflect the image in the same propositions, reversed left to right. There are two types of plane mirrors- one-way and two-way mirrors. They can be differentiated by a simple trick. Place your index finger on the mirror. If there is a gap between your finger and the reflection, it is a one-way mirror and if there is no gap, it is a two-way mirror. 
     In a two-way mirror, the person on the side of the non-reflective surface can view anything happening on the reflective side but the person on the reflective side cannot view what is on the other side. A one-way mirror on both sides is reflective, so it is most commonly found in trial rooms.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...
