color creation with primary and secondary colors

To do this expérience, we have need a white light as well as 6 different plastic filters which represent the 3 primary colors which are red, blue, green as well as the 3 secondary colors which are magenta, yellow and cyan.

this experiment shows how to create colors with the primary and secondary colors.
To create these colors we put 2 color filters in front of the light which create a new color. Let's take an example, if we put a filter of a primary color like red in front of the white light then a blue filter, when we bring together the blue and red beam we obtain a secondary color which is magenta. Then we do the same with the other primary color and we notice that its creating the secondary colors. Conversely, using the secondary colors gives the primary colors.
We notice that if we gather the beams of light from the three secondary colors we obtain black, conversely if we gather the beams of light from the three primary colors we obtain white

 Mister Fahrenheit create the Fahrenheit scale in 1708 with Copernic. The freezing point of water is 32 dégrée Fahrenheit, the boiling point is 212 degree Fahrenheit and thé human body temperature is 99 dégrée Fahrenheit. Fahrenheit is a scientist and he create thermometre, he use mercury for measure liquid.

The temperature can be measure in diferents scales, the degrees celsius, the degrees fahrenheit and the degrees kelvin . In degree celsius the boiling point of water is 100 degrees celsius and the freezing point of water is 0 degree celsius, in fahrenheit the freezing point of water is 32 degrees fahrenheit and the boiling point of water is 60 degrees fahrenheit. We can speak about the difference between the body temperatures, in degree celsius is 37 degrees celsius, and in fahrenheit is 96 degrees fahrenheit, but there is a way to translate the degrees fahrenheit in degrees celsius, the degree fahrenheit is equal to degrees celsius multiplie by 5 over 9 in parentheses and plus 32, and to get a degrees celsius in fahrenheit we need to do the next calcul ; fahrenheit minus 30 over 2 and we can get the temperature in degree celsius. We haven't talk about the last scale of temperature, the Kelvin, the kelvin is used by scientist, for have international unity of temperature, in kelvin the freezing point of water is 273 degrees kelvin.

First in degrees we have the temperature, the degree celsius, what we have in France, in Europe while in America and other places they have the Fahrenheit or the kelvins, to talk about mathematics, there are also relationships between the Fahrenheit, the kelvins and the Celsius.

We can also talk about degrees in mathematics or physics by calculating the value of an angle. The value of Fahrenheit and kelvin is significantly higher than the value of celsius, for example, the boiling point in Fahrenheit and 212 Fahrenheit while in Celsius the boiling point of the water is 100 degrees.

To begin they are 3 different scales to mesure temperature: the Celsius , the Fahrenheit and Kelvin.To convert a Fahrenheit into a Celsius we use the formula C =(F-32) x 5/9

And to convert a Celsius into a Fahrenheit we use the formula F = (Cx5/9)+32. But we can use a more simple formula F=Cx2+30 and C=F-30/2. The freezing point of water is 0°C or 32°F, and the boiling point of water is 100°C or 212°F. The body temperature is 96°F and 0K = -273°C. There are 3 states of matters : solid, liquid and gas.

What 's in a degree?

There are three differents types of degrees in the world :

-Celsius 

-Fahrenheit 

-Kelvin 

The boiling point of water is 100°C or 212°F. The freezing point of water is 0°C or 32°F. There are three different states of matters :solid, liquid and gas. In order to convert degrees Celsius in degrees  Fahrenheit, we can use this formula:F=Cx2+30.In order to convert degrees Fahrenheit in degrees Celsius, we can use this formula: C=F-30/2.In America they use feet and inches because Americans refuses to change tto the metric system because it will be to long and expensive. 

what's in a degree ?

Unit of measurement of temperature. The symbol is °C, equal to one hundredth part of the difference between the melting temperature of ice (0°C) and the boiling temperature of water (100°C) under normal atmospheric pressure. 

A degree can also be used to measure an angle. For exemple in triangle or in a square.

The kelvin (K) is the SI unit of temperature. It measures absolute temperature, a quantity defined by thermodynamics. This absolute temperature scale uses degrees Celsius, but starts at absolute zero, approximately -273°C. The melting temperature of ice is 273°K.

Unit of temperature measurement used in some countries (0°C corresponds to 32°F). Degree of heat measured via a value scale determined by the German physicist Daniel Fahrenheit in the 18th century and bringing the melting point of water to 32 degrees and that of its boiling to 212 degrees.
