Tonic Drinks: Gin And Tonic Water

Tonic water is a carbonated liquid which is commonly used as a mixer for many alcoholic beverages such as Gin and Tonic. Tonic water is often used in mixed drinks as it has a very bitter taste, as a result of the chemical called Quinine. This chemical was once used as a drug to treat Malaria and is found in the bark of Cinchona trees (Yoquinto, 2012). To assist in swallowing the drug, it was put into tonic water. A British Officer in colonial India during the 1800's found that mixing alcohol with the beverage made it much easier to swallow and tastier (Yoquinto, 2012). Malaria continues to be treated by Quinine today but only when the disease is resisting the treatment of other drugs. Quinine was also used to treat Nocturnal Leg Cramps but …show more content…
This is when an atomic particle is moved due to it being accelerated by an electric field. Electric and magnetic fields are created and move with a regular rhythm as a result of the moved particle (Lucas, 2015). They move at right angles to each other and are called photons. Photons travel at the fastest speed possible and these waves have their own characteristics such as wavelengths and frequencies (Lucas, 2015). The distance between two high points (known as peaks) or low points is known as wavelength and is measured in nanometres (nm). Frequency is the number of waves that pass a specific location in a certain period of time and is measured in hertz (Hz). The larger the wavelength, the smaller the frequency and vice versa. UV light is on the Electromagnetic Spectrum which is a large scope of different wavelengths and frequencies. Its seven sections are radio waves, microwaves, infrared, visible light, ultraviolet light, x-rays and gamma rays. The wavelengths of these are in order of the longest wavelength to the shortest and therefore the frequencies are in order of the lowest frequency to the highest. UV light has a wavelength range of 380nm (nanometres) to 10nm. Its frequency also ranges from 8 x 10^14 Hz to 3 x 10^16 Hz (Lucas, 2015). UV light is invisible to the human eye as its wavelengths are shorter of those of visible light. There are three subcategories for UV light. These being UVA, …show more content…
This is the type of UV light that has the longest wavelength and is the least harmful to the body. When an object such as a white T-shirt or anything fluorescent is placed under a black light, it glows very brightly. It isn't the object that is glowing, but the phosphors in the object. A phosphor is a substance that when it is exposed to UV radiation, it converts that energy into visible light, thus making the object glow (Harris, n.d.). This is known as fluorescence, which is the emission of light from the excited state of a molecule (Physikalisch-chemisches Praktikum I,
