Effects Of Microwave Radiation On Plant Growth

Plants can absorb a number of different length light waves, although not all of them are equal in power or energy which influences a plants growth. Approximately 80% of light that reaches a leaf is absorbed and depending on its wavelength, may excite chlorophyll pigments (reference text book). Plants absorb both red and purple light waves, however because purple wavelengths are shorter, they contain more energy.

Radiation (also known as nuclear radiation) refers to particles or waves emitted by radioactive substance. Nuclear radiation comes from the waves from a nucleus. Ionising radiation can

1. In 1895 the discovery of X-rays by the German scientist of physics, Wilhelm Roentgen, created an amazing step forward in the history of medicine. For the first time ever, the inner workings of the body could be made visible without having to operate.

Radiation is one of the main forms of energy (Pettigrew 1). In today’s environment we are only familiar with the basic types of radiation. These types are in the form of

1895 – X-rays were discovered accidentally by physicist Wilhelm Conrad Rontgen. Rontgen was working on a experiment and testing whether cathode rays could pass through glass. He noticed that a nearby tube emitted fluorescent glow of crystals. The air in the tube was released, high voltage applied, the same tube emitted a fluorescent glow. When Rontgen covered the tube in a heavy black paper, a green light could be seen. He concluded that a new light ray was being broadcast. Rontgen discovered that the light was very powerful and the same ray could pass through human tissue, but not through bones and metal objects. Medical applications were soon to follow.

Radiation was discovered in 1895 by Wilhelm Roentgen during a scientific experiment. Roentgen, classified radioactivity into three concepts: negative, positive, and electrically neutral. Radiation- is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Technology is created with radiation and humans are exposed to the aspect daily with tons or material; especially in the doctor’s office and everywhere else.

My investigative question is does microwaved water stunt plant growth? I was interested in learning more about this topic because I wanted to know if microwaves can put chemicals in your food causing you to not get all of the nutrients from the food. The purpose of my experiment is to see if water set to a boil on the stove, water set to a boil in the microwave, or water from both the microwave and stove will make plants grow more, also to see if the microwave puts bad chemicals into your food. My independent variable is the type of water used. My dependant variable is the height of the plant. My hypothesis is, if plants are grown with microwaved water then they will not grow as much as plants grown with water heated from the stove.

It’s a bird! It’s a plane! It’s Superman! In 1938, Action Comics #1, released the first Superman comic to the public.

X-rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with forty-eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods. Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode-rays on the luminescence of certain chemicals. Roentgen had placed a cathode-ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his darkened laboratory. He sent electricity through the cathodre-ray tube and noticed something strange his laboratory. He saw a flash of light

It was on November 8, 1895, that German physicist, Wilhelm Roentgen, accidently discovered the first x-ray when experimenting with his machine on his wife’s hand (Evolution

In 1899 Rutherford discovered radioactivity as well as alpha, beta and gamma rays, these were found while he was performing studies on the absorption of radioactivity, which was done by using thin sheets of metal and two components that he found, alpha and beta. Alpha radiation is absorbed by a centimetre of a few thousandths of metal foil. Beta radiation can progress through 100 times as much foil before it will be absorbed. While Rutherford found the two rays he yet found another shortly after called the gamma ray which can puncture as much as several centimetres of lead.

Radiology was invented in 1895 when Wilhelm Röntgen, a German Physicist, discovered x-rays. The technology

In this experiment, I tested the theory of how light would affect the growth of a bean plant. According to gardenguides.com, lack of light is detrimental to plant growth.”Plants that don't get enough light don't have the resources they require, and fail to bloom or fruit.” It is also stated that every plant will need a different strength of sunlight such as full sun, partial sun, or indirect sunlight (also known as full shade). Plants that receive inadequate amounts of sunlight will not thrive.The reasoning behind this is due to a process called Photosynthesis, stated in gardeningknowhow.com. Photosynthesis is a chemical process which converts energy in the form of light into a chemical energy which is a vital food source for plants to thrive.

The X-Ray was invented in 1895 by Wilhelm Conrad Roentgen. It all started with a vacuum tube called a Crookes tube, with this Roentgen noticed that by pressing a button that activated an electric current through it a shadow was projected onto a screen that showed the photograph of his wife’s hand with a ring

All this lights have equally conurbation towards plants growth but without any light then there is no process of photosynthesis which means there no plant growth at all. Photosynthesis is the procedure whereby radian vitality from the sun is changed over to the concoction bond vitality of glucose. In plants it happens in chloroplasts which concentrated cells. Chlorophyll atoms are instrumental in the first step, which is the change of light vitality to the substance bond vitality of ATP. Vitality to change carbon dioxide and hydrogen to glucose is then given by the ATP. Oxygen is discharged as a waste result of procedure. The reaction is shown below:
