| [#25] 電陶爐好用嗎？ 電陶爐多咗把風扇，煲底要夠平貼爐面，否則唔夠熱，傳熱唔夠普通電爐匀巡，惟一好處就是用數碼電路控制，輕觸開關，整體效率始終不及普通電爐 |

| [#20] 電陶爐好用嗎? https://en.wikipedia.org/wiki/Electromagnetic_radiation In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy.[1] It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.[2] Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light, which, in a vacuum, is commonly denoted c. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The wavefront of electromagnetic waves emitted from a point source (such as a light bulb) is a sphere. The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by either its frequency of oscillation or its wavelength. Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.[3] Electromagnetic waves are emitted by electrically charged particles undergoing acceleration,[4][5] and these waves can subsequently interact with other charged particles, exerting force on them. EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matter with which they interact. Electromagnetic radiation is associated with those EM waves that are free to propagate themselves ("radiate") without the continuing influence of the moving charges that produced them, because they have achieved sufficient distance from those charges. Thus, EMR is sometimes referred to as the far field. In this language, the near field refers to EM fields near the charges and current that directly produced them specifically, electromagnetic induction and electrostatic induction phenomena. In quantum mechanics, an alternate way of viewing EMR is that it consists of photons, uncharged elementary particles with zero rest mass which are the quanta of the electromagnetic force, responsible for all electromagnetic interactions.[6] Quantum electrodynamics is the theory of how EMR interacts with matter on an atomic level.[7] Quantum effects provide additional sources of EMR, such as the transition of electrons to lower energy levels in an atom and black-body radiation.[8] The energy of an individual photon is quantized and is greater for photons of higher frequency. This relationship is given by Planck's equation E = hν, where E is the energy per photon, ν is the frequency of the photon, and h is Planck's constant. A single gamma ray photon, for example, might carry ~100,000 times the energy of a single photon of visible light. The effects of EMR upon chemical compounds and biological organisms depend both upon the radiation's power and its frequency. EMR of visible or lower frequencies (i.e., visible light, infrared, microwaves, and radio waves) is called non-ionizing radiation, because its photons do not individually have enough energy to ionize atoms or molecules or break chemical bonds. The effects of these radiations on chemical systems and living tissue are caused primarily by heating effects from the combined energy transfer of many photons. In contrast, high frequency ultraviolet, X-rays and gamma rays are called ionizing radiation, since individual photons of such high frequency have enough energy to ionize molecules or break chemical bonds. These radiations have the ability to cause chemical reactions and damage living cells beyond that resulting from simple heating, and can be a health hazard. |

| [#16] 電陶爐好用嗎? 輻射可以用來形容能量傳輸方式，如太陽在真空宇宙傳送能量，亦可以是形容粒子或電磁波。 紅外線是電磁波之一種，以輻射方式傳送。電磁爐的電磁波也是。 另一種是放射粒子，如Alpha,beta,gamma particles. |

| [#14] 電陶爐好用嗎? 中學物理都有講太陽傳熱俾地球是靠幅射。有害的幅射是gamma高能量之類，任何家用爐都應該製造唔到高能量幅射的。 |

| [#13] 電陶爐好用嗎？ 唔止咁，鑊入面嘅食材都吸收隻鑊嘅紅外線，再轉發部份出來。 當我地食那些食物時，嘴巴都吸收食物的紅外線。  最後修改時間: 2018-10-17 14:41:18 |

| [#11] 電陶爐好用嗎？ 紅外線個鑊底擋唔到? --------------- 電陶爐發射嘅紅外線，個鑊吸咗大部份，其它從鑊邊輻射出來。 個鑊吸咗電陶爐發射嘅紅外線之後，會從隻鑊再發射番部份出來。 kakaka~~~ |
