X-radiation (which is composed of X-rays‚ hence the name) falls under electromagnetic radiation. X-rays and gamma rays are sometimes confused‚ but they are different‚ as X-rays are emitted by electrons outside the nucleus whilst gamma rays are produced inside the nucleus. X-rays have extremely small wavelengths (10-0.1 nanometers)

is called emissivity‚ is a number between 0 and 1. This depends on the characteristics of surface of radiation material. The color of the light emitted by the hot object is also related to temperature. As the temperature increases‚ the electromagnetic radiation reaches a peak at higher frequency. An ideal black body would release all kinds of radiation when heated but the peak radiation depends on the temperature. It is found experimentally that the wavelength at the peak of the spectrum‚

Microwaves are a type of electromagnetic waves that place between radio waves and microwaves on the electromagnetic spectrum. The longer the wavelengths‚ the lower the energy frequency. A typical microwave oven has a wave frequency of 2‚ 450 megahertz (M. Brian‚ 2000). Water‚ sugar and fats only absorb waves in this frequency

mechanical energy. Energy is transferred from one place to another with waves. All waves have amplitude‚ wavelength‚ and frequency. The electromagnetic spectrum is the range of wavelengths or frequencies over which electromagnetic radiation extends. In the electromagnetic spectrum the visible light falls in the middle. Visible light waves are the only electromagnetic waves we can see. We see the waves as all the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength

Market 2014-20180280035Electromagnetic Compatibility (EMC) is the ability of electrical equipment to perform efficiently in an electromagnetic environment without being affected or influenced by other devices in its proximity. EMC shielding is a protection provided to electrical and electronic devices to protect them from EMI. EMI refers to the phenomenon where electromagnetic radiation affects the performance of electrical and electronic equipment. EMC shielding is used across many industries because

The progressive relaxation hypnosis is simple and reliable‚ and every hypnotist should learn the progressive relaxation induction. Progressive relaxation induction is also called the Jacobson relaxation method. The basic progressive muscle relaxation script technique (PMR) is to tense and then relax each muscle group‚ progressing from the head to the feet‚ while suggesting deeper

convenient‚ but they can also be very dangerous. They emit a type of radiation called radio frequency (RF) that has been shown to damage genetic material in blood cells‚ which can cause cancer. Radio frequency energy is a form of electromagnetic radiation. Electromagnetic radiation are categorized into two type: ionizing and non-ionizing. Ionizing radiation are found in x-rays‚ cosmic rays‚ and radon. Non-ionizing radiations are found in radio frequency and extremely low-frequency or power frequency

important one: microwaves and their effect on plants. Microwaves are going to be the focus of our study because of the drastic effects that they have‚ not only on humans and different mammals but on plants. In brief‚ we can say that microwaves are electromagnetic waves with wave length longer than those of terahertz (THz) frequencies‚ but relatively short for radio waves. There are lots of sites contaminated by microwave radiation from cellular radiation‚ power plants and high voltage towers‚ etc….. These

logic1. 3.3 Fallacies of Weak Induction: 3. Fallacies of weak induction a fallacy of weak induction occurs when an argument’s premises are not strong enough to support the conclusion. The premises are logically relevant‚ but that isn’t enough for them to be supportive enough. These fallacies also involve an emotional appeal to make their case. 4. Different types of weak induction fallacies Appeal to unqualified authority (Argumentum ad Verecundiam) this fallacy affects arguments from authority
