A simple way to locate to image in a plane mirror without using light rays is to measure the distance of the object itself to the mirror and then draw a dotted line that is equal to the distance of the object-mirror on the other side. Then connect the sides to the end of the line. i had to do this in science today :)
the law of incidence is equal to the angle of reflection. draw a line as a surface. then draw a line going straight up from the center. now draw a line going from one side to the intersection of the surface and the dotted line. this line is the line of incidence. draw another line on the other side, like a mirror. this second line is the line of reflection. delete the middle line. the left line, the line of incidence, is mirrored to create the line of reflection. the angle from the incidence line to the surface is equal to the angle from the reflection line to the surface.
Corrected: Only with some peculiarsubstances like ice contract on melting and expand on freezing. Since pressure also contracts ice, doing the same work of melting, the melting point of ice DECREASES with INCREASE of pressure.Added:In 'Related links' attached to this page (lower left corner) a diagram-picture of"Melting point: Temperature and Pressure" is shown asGreen line for most 'normal' solidsand ofWater-Ice: it is the Green-Dotted line.
Work is Force multiplied by distance. W=Fd The units of work are Joules (J). We can check the above equation by checking that the units are correct. Below is the unit cancellation for the above equation. J=N*m ( 1 J = 1 N*m. This is the definition of a joule)
# There are a couple of other interesting things about the invention of the light bulb: While most of the attention was on the discovery of the right kind of filament that would work, Edison actually had to invent a total of seven system elements that were critical to the practical application of electric lights as an alternative to the gas lights that were prevalent in that day. These were the development of: ## the parallel circuit, ## a durable light bulb, ## an improved dynamo, ## the underground conductor network, ## the devices for maintaining constant voltage, ## safety fuses and insulating materials, and ## light sockets with on-off switches. Before Edison could make his millions, every one of these elements had to be invented and then, through careful trial and error, developed into practical, reproducible components. The first public demonstration of the Thomas Edison's incandescent lighting system was in December 1879, when the Menlo Park laboratory complex was electrically lighted. Edison spent the next several years creating the electric industry. The modern electric utility industry began in the 1880s. It evolved from gas and electric carbon-arc commercial and street lighting systems. On September 4, 1882, the first commercial power station, located on Pearl Street in lower Manhattan, went into operation providing light and electricity power to customers in a one square mile area; the electric age had begun. Thomas Edison's Pearl Street electricity generating station introduced four key elements of a modern electric utility system. It featured reliable central generation, efficient distribution, a successful end use (in 1882, the light bulb), and a competitive price. A model of efficiency for its time, Pearl Street used one-third the fuel of its predecessors, burning about 10 pounds of coal per kilowatt hour, a "heat rate" equivalent of about 138,000 Btu per kilowatt hour. Initially the Pearl Street utility served 59 customers for about 24 cents per kilowatt hour. In the late 1880s, power demand for electric motors brought the industry from mainly nighttime lighting to 24-hour service and dramatically raised electricity demand for transportation and industry needs. By the end of the 1880s, small central stations dotted many U.S. cities; each was limited to a few blocks area because of transmission inefficiencies of direct current (dc). The success of his electric light brought Thomas Edison to new heights of fame and wealth, as electricity spread around the world. His various electric companies continued to grow until in 1889 they were brought together to form Edison General Electric. Despite the use of Edison in the company title however, he never controlled this company. The tremendous amount of capital needed to develop the incandescent lighting industry had necessitated the involvement of investment bankers such as J.P. Morgan. When Edison General Electric merged with its leading competitor Thompson-Houston in 1892, Edison was dropped from the name, and the company became simply General Electric. ightbulb
Dotted Border was created in 1776.

Double yellow lines, which are solid and not dotted, indicates a no passing zone.
The dotted line between two connectors indicates a relationship. The relationship is not a permanent one, hence the line is dotted rather than solid.

it's depends on what kind of software you are using, such as photoshop, if you selected a layer, it show nothing around the edge, but if you selected a specify object, it shows a moving dotted line around the graphic. For AI ( Adobe illustrator ) it shows a blue line with some small square on each corner and on the middle of each line.

You can put in dotted border lines. The regular lines that show rows and columns are known as gridlines, though they are solid, not dotted. Borders are set by the user and can be put in with different styles.
