Electromagnetic Radiation

Electromagnetic (EM) radiation is the energy transmitted through space or a material medium in the form of electromagnetic waves. The frequency range of such waves is tremendous, and is shown by the electromagnetic spectrum. These waves include radio waves, microwaves, infrared waves, visible light waves, ultraviolet (UV) waves, X-rays, and gamma rays.

Does a flashlight have radiation?

User Avatar

Asked by Wiki User

Yes, although probably not the kind you're thinking about. Microwaves use electromagnetic radiation to heat food. If the microwave is properly constructed and not damaged, none of that radiation escapes.

Are gamma rays the deadliest rays?

User Avatar

Asked by Wiki User

Yes, gamma rays are considered to be the most dangerous type of radiation because they have the highest energy and can penetrate deeply into the body. Exposure to excessive amounts of gamma rays can cause severe damage to cells and DNA, leading to serious health effects such as radiation sickness, organ failure, and an increased risk of cancer.

What is Electromagnetic interference and type?

User Avatar

Asked by Wiki User

Electromagnetic interference (EMI) refers to the disruption or distortion of the normal operation of electronic devices caused by the presence of electromagnetic energy from external sources. There are two main types of EMI: conducted and radiated. Conducted EMI occurs through physical conductors like power lines or cables, while radiated EMI is transmitted through the air as electromagnetic waves.

How fast does electromagnetic radiation particles travel?

User Avatar

Asked by Wiki User

Electromagnetic radiation, such as light, travels at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is considered to be the maximum speed limit in the universe.

What kinds of radiation do film badges monitor?

User Avatar

Asked by Wiki User

Film badges are typically used to monitor ionizing radiation, which includes X-rays and gamma rays. These badges contain a film that darkens when exposed to ionizing radiation. They do not monitor non-ionizing radiation like radio waves or visible light.

How many km hr do gamma rays travel at?

User Avatar

Asked by Wiki User

Gamma rays travel at the same speed (in a vacuum) as all Electromagnetic radiation, that is 2.99 792 458 x 108 m/s. There are 1000 metres in a kilometre, making 2.99 792 458 x 105 km/s. Since there are 3600 seconds in an hour gamma rays travel at 1.079252849 x 109 km/hr or 1,079,252,849 km/hr. (roughly a billion)

What type of electromagnetic radiation is used to treat the waste water?

User Avatar

Asked by Wiki User

Ultraviolet (UV) radiation is commonly used to treat waste water. UV radiation in the germicidal range (between 200-300 nanometers) is effective in destroying harmful microorganisms present in the water. This process helps to disinfect the waste water before it is released into the environment.

A range of wavelengths of light that increases from one end to the other

Is Armstrong unit a measure of length?

User Avatar

Asked by Wiki User

Not quite. I believe you are referring to the angstrom or ångström, which is a unit of length equal to 1/10,000,000,000 of a meter (or 0.1 nanometers or 100 picometers).

This measure of length is denoted by the Swedish letter Å, however its use is declining due to the popularity of the nanometer.

What part of the electromagnetic spectrum is most absorbed by water?

User Avatar

Asked by Wiki User

Water is cyan because it absorbs red light. The froth in the waves is white because, like clouds, it is composed of variety of tiny water droplets that scatter light of all the visible frequencies.

Water is transparent to light of nearly all the visible frequencies, it strongly absorbs infrared waves. Water molecules resonate to the frequencies of infrared. Energy of the infrared waves is transformed into internal energy in the water, which causes red light to be a little more strongly absorbed in water than blue light.

Electromagnetic waves that stimulate the sensation of color when the vibrations interact with the cone-shaped receiving antennae in the retinas of our eyes. Our eye-to brain interactions produce the beautiful colors we see.

Why are all gamma rays shorter than x-rays?

User Avatar

Asked by Wiki User

Gamma rays are more energetic because they have a higher frequency. The operate on the order of 10^19 Hz, whereas X-ray frequencies are typically an order of magnitude or two smaller.

Energy is related to frequency by Max Planck's equation E=hf, where h is Planck's constant (6.626x10^-34 Js) - we see this product yields the unit Joules.

Frequency and wavelength are easily related knowing light travels at a finite speed of about 300,000,000 m/s-

300,000,000 m/s = wavelength (m) * frequency (1/s)

If a gamma ray has 10^19 Hz frequency,

( 300,000,000 m/s ) / ( 10^19 s^-1 ) = wavelength (m) =~ 3x10^-11 m = 0.03 nm

If an x-ray has 10^17 Hz frequency,

( 300,000,000 m/s ) / ( 10^17 s^-1 ) = wavelength (m) =~ 3x10^-9 m = 3 nm

The higher frequency photon can be thought of as more energetic since more successive wavelengths pass through a given point per second.

Wave length of x ray?

Asked by Wiki User

There is some confusion here.

Wavelengths are measured in units of length, such as meters, kilometers, nanometers, etc.

Frequency is measured in hertz.

What are the sources of X rays and gamma rays?

User Avatar

Asked by Wiki User

X rays and gamma rays are both in the electromagnetic spectrum, gamma rays can come from nuclear bombs (which can pass through metals and concrete). X rays are used in many places, in the hospital, the air port, and many more, I don't really know what their source is I'll have to check in my science encyclopedia.

Asked by Wiki User

Gamma rays are electromagnetic radiation and have very high penetration power. Gamma rays are similar to UV rays and x-rays in the sense that all of them are forms of electromagnetic radiations.

How dangerous is the threat of Water contamination from Nuclear waste?

User Avatar

Asked by Wiki User

If you put nuclear waste in a situation where groundwater can flow over it on the way to a water course, you will obviously get contamination. Nuclear waste stores have to be very carefully considered to find locations that are safe from water access.
