How are electromagnetic waves hazardous
WebThese waves could have any frequency, but for one special region, the region is the visible spectrum. So we call the regional frequencies and wavelengths that Electromagnetic waves can have the Electromagnetic Spectrum, and there is a lot to learn about the Electromagnetic Spectrum. Let me just show you really quick.
How are electromagnetic waves hazardous

WebAbsorption occurs when photons from incident light hit atoms and molecules and cause them to vibrate. The more an object's molecules move and vibrate, the hotter it becomes. This heat is then emitted from the object as thermal energy. Some objects, such as darker colored objects, absorb more incident light energy than others.

WebPower density is defined as power flow per unit area. For example, power density is commonly expressed in terms of watts per square meter (W/m 2 ), milliwatts per square centimeter (mW/cm 2 ), or microwatts per square centimeter (µW/cm 2 ). One mW/cm 2 equals 10 W/m 2, and 100 µW/cm 2 equal one W/m 2. WebPotential health consequences If electric, magnetic, and electromagnetic fields (EMF) are powerful enough, they can cause short-term health impacts. Exposure to powerful …
