How far does infrared reach?
How far does infrared reach? Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Below infrared is the microwave portion of the electromagnetic spectrum. Does infrared have […]
How dangerous is mobile phone radiation?
How dangerous is mobile phone radiation? Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, “there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. […]
Why is a paperclip attracted to a magnet?
Why is a paperclip attracted to a magnet? Why do magnets attract paper clips? Magnets attract paper clips because magnets have a magnetic field, which creates a force, that pulls on other ferromagnetic materials. A paper clip is usually made of steel wire. Iron is a ferromagnetic material that is attracted by magnets. Can a […]
Why is the charge of the electron negative?
Why is the charge of the electron negative? Electric charge is a physical property of matter. It is created by an imbalance in a substance’s number of protons and electrons. The matter is positively charged if it contains more protons than electrons, and it is negatively charged if it contains more electrons than protons. What […]
Why are water cycle processes important?
Why are water cycle processes important? The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn’t naturally recycle itself, we would run out of clean water, which is essential to life. What are the three main […]
