Electromagnetic Radiation

rem is an acronym for roentgen equivalent man, the unit used to measure the amount of radiation that results in the same amount of human tissue damage as that caused by one roentgen of X-rays.

Well techinichally it is just a radiation that comes from the sun and the readiation is a electromagnetic field

A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.

Rainbows are formed through refraction. The refraction happens through the rain drops, causing the light (which is made up of a spectrum of colours) to split and causes a rainbow.

Richard Of York Gave Battle In Vain -> Red, Orange, Yellow, Green, Blue, Indigo and Violet. This is the order in which it refracts.

Ozone (O3) in the stratosphere absorbs ultraviolet (UV) radiation, particularly UV-B and UV-C. This absorption plays a crucial role in protecting Earth's surface from harmful UV radiation. Additionally, certain greenhouse gases like methane and nitrous oxide can also absorb some UV radiation in the upper atmosphere.

The light bulb gives light be heating the filament. Roughly speaking, it is emitting black body radiation. Plank's Law gives you the formula.

Electromagnetic radiation is common in living organisms. One example is infrared radiation (heat) given off by warm bodies. And we know that critters like sharks can sense magnetic fields generated electromagnetically by other critters they are searching for.

Electromagnetic. Or you might be looking for transverse.

Frequency of electromagnetic radiation = (speed of light) / (wavelength) Speed of light in vacuum = 300,000,000 meters/sec (rounded) Frequency = (300,000,000 meters/sec) / (5 x 10-6 cm) = (3 x 108 m/s) / (5 x 10-8 m) = 0.6 x 1016 = 6 x 1015 Hz.

Because the theory is that this is what the form is. If it were a longitudinal or compressional form (such as sound) it would need to travel through a medium of some sort to compress the particles of that medium. But electromagnetic radiation can travel even in a vacuum.

Different colors of light are associated with different wavelengths. For example, red light has a longer wavelength, around 620-750 nanometers, while violet light has a shorter wavelength, around 380-450 nanometers. The colors of the visible spectrum, in order of increasing wavelength, are violet, blue, green, yellow, orange, and red.

such objects are identified with the suffix -escence where the root word is the element that is responsible for the light.

When you have Florine as the source of the light you have fluorescence.

When you have phosphorus as the source of the light you have phosphorescence.

and so on.

theoretically every element could contribute to this.

Some common types of electromagnetic coils include solenoid coils, toroidal coils, and air core coils. Solenoid coils consist of a tightly wound helical coil used to generate a magnetic field when current passes through them. Toroidal coils are circular coils wound around a core, often used for inductors in electronic circuits. Air core coils do not have a ferromagnetic core and are used when minimal magnetic interference is desired.

Infrared radiation has longer wavelengths than the human eye can detect. These wavelengths are longer than those of visible light, allowing infrared radiation to be used for thermal imaging and night vision technology.

Two objects can transfer energy to one another through various mechanisms, such as collisions, electromagnetic radiation, or heat conduction. For example, in a collision between two objects, kinetic energy can be transferred from one object to another. In the case of electromagnetic radiation, energy can be transferred between objects through the emission and absorption of photons.

any type of seed get affected but, it depends by the thickness of the seed coat. if it is to thick it will have no effect at all. if it is too thin the seed will burn up and die. if it is normal i will have some changes but the seed will not die.

The range of wavelengths for X-rays is typically between 0.01 to 10 nanometers. X-rays have shorter wavelengths and higher energy compared to visible light, making them suitable for medical imaging, security screening, and materials analysis.

Infrared light has a wavelength just outside the visible red wavelength. This type of light is longer in wavelength than red light, making it invisible to the human eye but detectable by special cameras or sensors.

Ultraviolet light extends for quite a ways up the electromagnetic spectrum after visible violet ends. Its frequencies are higher. Wavelengths from 400nm to 50nm covering 4 groups of UV.

Light waves are used for various applications such as communication (fiber optics), lighting, photography, and medical imaging (X-rays, MRI). They are also crucial in technology like lasers, spectroscopy, and sensors.

No, radiation is not a gas. Radiation refers to the emission of energy in the form of waves or particles from a source. Gases are made up of individual atoms or molecules that can move and flow freely.

this angle is called the critical angle of a substance. To work it out you must know the refractive index of that substance.

because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....

High-energy radiation such as gamma rays and X-rays are stopped in the ionosphere by interactions with the particles and magnetic fields present in this region of the Earth's atmosphere. The ionosphere acts as a shield, absorbing and scattering these types of radiation before they can reach the Earth's surface.
