( PERSONAL LETTER )

            January 11, 2020
Dear, Balqis
How are you? I hope you are well I am writing this latters to tell about my holiday experience. During the holiday, I went on vocation with my family. I went around the Malang City with my brother and sister. I toured to shop and explore culinary in the city. On the way I daserved the surrounding environment. I feel the air is quite cool because the roodside of the city is already planted with trees. I think the trees are enough to reduce air pollution due to the number of vehicles. I hope that in the future it can be even better. You can also give me enough to get here first letter form me. I am waiting for your replay.
Thank you.

                                                              King regards

                                                                   Citra’s

                              About Cigarettes
     One of the most common problems now killing people, all over the world, is smoking.  Many people start this terrible habit because of stress, personal problems and high blood pressure.  Some people start showing off or some people want to enjoy it.  One cigarette can cause someone else to smoke, which can cause great addiction.  When someone smokes, they not only hurt themselves, but other people around them.  Smoking does many terrible things to the human body that most people are unaware of.  Almost everyone knows that smoking causes cancer, and heart disease;  that it can shorten your life by 10 years or more;  and that habit can cost thousands of smokers a year.  So why do people still smoke?  The answer is clear, addictive.  Smoking is a habit that is difficult to stop because tobacco contains nicotine, which is very addictive.  There are several effects and causes of smoking;
First of all, teens smoke because they want to be healthy.  Teenagers see their friends smoking and they think it makes them look cool or independent plus them.  Feel no tension plus worry.  The first cause of smoking namely nicotine is an addictive and dangerous substance contained in cigarettes.  This reduces tension and is also believed to have a calming effect on anxious and worried people.  Even though, people smoke when they are depressed, lonely or bored and it helps them reduce stress.  The second main cause of smoking is "psychological" (MENTAL) which seems to be a very important factor for people to get the habit.  In many cases, smoking begins at a young age due to high blood pressure, tobacco.  Many people who start smoking have family members or close friends who smoke.  Smoking is like a slow death.  There are various examples of smoking.  Smoking causes lung cancer, heart disease, stroke, asthma, and various other diseases.  Smokers experience more coughs and colds compared to nonsmokers.  Aside from influencing yourself, it also has a negative impact on others around smokers who are also known as passive smokers.  Also every pregnant woman who is exposed to secondhand smoke will have a higher risk of having an abnormal baby.  Have you ever wondered what's in cigarettes that millions of people like to smoke every day?  There are more than 4000 toxic substances in a cigarette.  Some of them are: Arsenic (found in rat poison), Acetic acid (found in hair dye developers), Ammonia (found in household cleaners), Benzene (found in rubber cement), Butane (found in lighter liquids),  Carbon Monoxide (found in car smoke). Smoking is a habit that is difficult for individuals to avoid.  Many people make preparations for months in their efforts to get rid of the habit. Many teenagers smoke because of depression and stress, but they must know now that smoking kills you from the inside, there are many ways to solve such problems, but one of them is they are NOT  smoke.  It's just madness and it will give you cancer.  People like teenagers don't think.  BAD SMOKING FOR YOU !!!!!!
Always try to avoid what your friends say about smoking, just say Alhamdulillah with what Allah has given you, So Alhamdulillah for everything, and please stop smoking.

                                    Rainbow
      Sunlight is a polychromatic light (consisting of many colors). The white color of sunlight is actually a combination of various light with different wavelengths. The human eye is able to perceive at least seven colors of sunlight, which will be seen in the rainbow: red, orange, yellow, green, blue, indigo and violet. This wavelength of light forms a ribbon of parallel lines, each nuanced color with a color next to it. This band is called the color spectrum. In the color spectrum, the red lines are always on one side and blue and violet on the other, and this is determined by the difference in wavelength.
Rainbow is a natural phenomenon that is so impressive. This phenomenon often appears after rain. Rainbow is an arc spectrum which is so large and occurs because the drops are refracted by sunlight. When the sun is shining and the light passing through water droplets, then you will see a refraction that causes a wide variety of colors. Light is refracted like light passing through a glass prism.
How does rainbow happen in detail? All the happenings begin when the sunlight passing through the raindrops. Then the light is deflected to the center of the droplet. The white light, now separated from each other into a spectrum of colors. The process does not stop there. The colors that have been separated, then separate again into the very small portions. There is more light separated from each other in the droplets. Then there are more curved and finally those color form a light curve called a rainbow.
Rainbow is nothing but an arc of a large circular spectrum of color that occurs due to refraction of sunlight by water grains. When sunlight passes through water droplets, it refracts like when it penetrates a glass prism and comes out into a rainbow color spectrum. So inside the water droplets, we have got different colors lined up from one side to the other. Some of this colored light is then reflected from the far side of the water droplets, returning and exiting again from the water droplets. Light comes back from water droplets in a different direction, depending on the color. The colors on this rainbow are arranged in red at the top and purple at the bottom of the rainbow.
Rainbow is seen as a bow from the surface of the earth because of the limited viewing angle of the eye, if the vantage point in a high place, for example from an airplane, can be seen as a complete color spectrum in the form of a circle. The rainbow can only be seen when it rains together with the sun shining but from the opposite side of the observer. The position of the observer must be between the sun and the droplets of water with the sun behind the person. The sun, the eye of the observer, and the center of the rainbow arc must be in a straight line.
Can we make a rainbow? Of course. There are at least two ways that you can do to make a rainbow. First, you can use a spray containing water. We know that rainbows occur when sunlight passing through the raindrops. So, we make our own rain droplets from the water spray. In the morning or afternoon, spray water under the sun, then see the water droplets flying. Spray lots of water and you will see a small rainbow that you can touch easily.
Second, use pieces of video discs then reflected the light of the sun, and navigate to the wall or ceiling of your house. On the ceiling or the wall, you will see a colorful light that has the same color as the rainbow.
That’s the definition of rainbow, how does it happen, and how we can make it true.
