![]() Gamma rays are ionising radiation and can therefore destroy molecules and connections in atoms and cause damage to tissues. Gamma radiation is very energy rich and penetrates most solid materials. This type of radiation does not penetrate bones, and is therefore very suitable for photographing the skeleton of humans and animals. X-rays are energy rich radiation and can penetrate soft tissue. From the colour red with the longest wavelength (and thus least energy) to the colour violet which has the shortest wavelength (and the highest energy): ![]() Visible light has a whole spectrum of colours. Different cameras and surveillance equipment such as motion detectors can react to infrared radiation. energy that is propagated through free space or through a material medium in the form of electromagnetic waves, such as radio waves. Physical bodies with temperatures around room temperature and above will emit radiation in the infrared area. In this spectrum you will, for example, find radar and microwave ovens. Microwaves are less widespread and are used where the transmitter and the receiver are closer to each other. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules. Radio waves are used to transmit wireless signals to TVs, radios and mobile phones through the air. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Waves with a long wavelength spread well beyond their surroundings. In the figure above, both the frequency and wavelength are included, and the correlation between these is given in the equation c = λ x f, where c is the speed of light, λ is wavelength and f is frequency. These are waves of different frequency and wavelength dependent on the origin. When an electrical charge changes its energy condition it leads to moving waves. EMR is energy transmitted through empty space or through matter as electromagnetic waves. This is because the heat energy is radiated in the form of thermal energy that heats up the surrounding air passing by it.Visible light, radio waves and X-rays are examples of electromagnetic radiation (EMR). Sitting near the campfire, you feel warm being around. Read more on 10+ Example Of Mechanical To Thermal Energy: Detailed Explanations. The energy is due to the vibrational energy produced on the collision of electrons in the electric field inside the device which is radiated in the form of thermal energy. The energy generated inside the devices is given out in the form of thermal energy thus heating the devices. Many electronic devices get warmer when used over the long. ![]() This is also because the Smartphone carries many electronics and sensors inbuilt. ![]() You must have noticed that your mobile screen gets hot on overusing. This emission of electromagnetic waves results in thermal radiation causing the devices to heat up. The mobile phone emits radiation in the range of a radio wave while in use. This energy is further radiated in the surrounding, hence feeling warm near the rocky areas. The sunlight is accompanied by the radiant energies photons is converted into thermal energy thus raising the temperature of the rock. When the intensity of the light is more and radiations incident on the surface of the rock is high, the temperature of the surface of the rock and near region become very high.
