A convex mirror is the kind of mirror used for security in stores, and is also the kind of mirror used on the passenger side of many cars ("Objects in mirror are closer than they appear."). A convex mirror will reflect a set of parallel rays in all directions; conversely, it will also take light from all directions and reflect it in one direction, which is exactly how it's used in stores a cars.

LIGHT

Reflection and Refraction are two important Phenomena of Light. Concave Mirror and convex mirror are called spherical mirrors.

Dispersion of,light occurs when it passes through a prism.

If the inside of a spherical mirror is silvered then it is a concave mirror.concave mirror is used as a shaving mirror. Concave mirror is used as a reflector in torches,head lights of cars and other vehicles.

Light is known to behave in a very predictable manner. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection.

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This called the refraction index. The refractive indices of water is 1.33.petroleum is 1.38.

A plane mirror is simply a mirror with a flat surface; all of us use plane mirrors every day, so we've got plenty of experience with them. Images produced by plane mirrors have a number of properties, including:

1.the image produced is upright

2. the image is the same distance from the mirror as the object appears to be (i.e., the image distance = the object distance)

the image is a virtual image, as opposed to a real image, because the light rays do not actually pass through image.

A World War II vintage periscope nearby is very popular with kids of all ages.. We use it to sink houses and buildings in Hollywood. The periscope extends through the ceiling and projects 22 feet above the roof.

Kaleidoscope is the ultimate in user interface customization for the Macintosh, letting you switch between completely different interface designs provided by plug-in modules called "Schemes".
