Is light the same as electromagnetic radiation?
Yes, it is. Electromagnetic (EM) waves have frequency and amplitude (as well as polarity and a couple of other things), and because it has frequency, it can be distributed across a range of frequencies, or a spectrum - an electromagnetic spectrum. Light is a range of frequencies in what we call the optical or visible range. It is bounded on the lower end (lower frequency, lower energy, longer wavelength) by infrared (IR) light, and on the upper end (higher frequency, higher energy, shorter wavelength) by ultraviolet (UV) light.Yes. Light is also called a "electromagnetic wave"
What is the relationship between heat and infrared radiation?
The relationship between heat and infrared radiation is that one is generated from the other.Heat is thermal energy. It is the collective energy of movements of atoms, molecules, and electrons within, and dependent upon, a bounded system of matter. This form of energy is not capable of moving through a vacuum.Infrared radiation is electromagnetic radiation or light energy, photon emissions from any mass who's temperature is above absolute zero. It is energy that has been converted from thermal energy and, once generated, is independent of matter and capable of moving through a vacuum
What gives off electromagnetic radiation?
Many things give off electromagnetic radiation. Cell phones, the body, x-rays, and supposedly ghosts and spirits. EMF detectors (or electro-magnetic-field detector) are also supposed to pick up electromagnetic radiation given off by anything it's pointed at.
Where do electromagnetic waves come from?
A spectrum is a representation of the range of frequencies/wavelengths present in electromagnetic radiation. It may be plotted as the power or intensity on the vertical axis, and the wavelength or frequency on the horizontal axis. When talking about the electromagnetic spectrum it is sometimes presented as a chart or table showing the range of frequencies/wavelengths that are covered by electromagnetic radiation. Thus it represents radiation from radio frequencies through infra red, visible light, ultraviolet light, x-rays and gamma radiation. Where does it come from? The first link below shows the history of "spectrum" which was originally used to refer to the colours of light when split up by a rainbow or prism. It was later used by analogy to refer to "a range of objects". I guess that someone just wanted to make a chart showing how the various radiation types are related.
All electromagnetic waves have the same?
In a vacuum, all electromagnetic waves have the same propagation speed of c = 300,000,000 meters per second (the speed of light). All of these waves, however, may have different frequencies and thus wavelengths. The speed of a wave is related to its frequency and wavelength by the relation (speed) = (frequency) X (wavelength) Since the speed of electromagnetic waves in a vacuum is constant, the frequency and wavelength are "inversely proportional" to one another. This means that cutting the frequency of a wave in half makes its wavelength double, and vice versa.
What do all types electromagnetic radiation have in common?
They travel at the speed of light (c = 3*108 m/s)
Do radio waves and light waves travel at the same speed?
Yes. They're both forms of the same thing, called "electromagnetic radiation". Other forms you may have heard of include heat, microwave, ultraviolet, and X-rays. All the same thing, and travel at the same speed.
Why do gamma rays travel at the speed of light?
Gamma rays travel at the speed of light because both light and gamma rays are variants of the same thing: electromagnetic radiation.
What is the same for all types electromagnetic radiation?
They all travel at the SPEED OF LIGHT.
How does the speed of visible light compare with the speed of gamma ray?
Gamma radiation is the fastest, as it is light. speed of gamma radiation = c (light speed) speed of beta radiation < c ( below light speed ) speed of alpha radiation < c/10 ( far below light speed )
Which type of nuclear radiation travels the fastest?
All electromagnetic radiation travels at the same speed. We usually call it "the speed of light" but it's the same for all other forms of electromagnetic waves.
Is light the same as refraction?
No. Light is energy in the form of electromagnetic radiation. Refraction is a physical process that affects any wave.
Is light a radiation or a particle?
Yes, it acts like whichever your experiment is testing for. This is one thing about quantum mechanics that confuses many people (and probably cannot be fully understood by the human mind). Also, its not just electromagnetic radiation, but matter acts the same way (sometimes a wave sometimes a particle).
Which light has the greatest speed?
In a vacuum, all colors of light - as well as other electromagnetic radiation - travel at the same speed, the so-called "speed of light".
Is infrared radiation part of the electromagnetic radiation?
Yes it is. Infrared is the same physical phenomenon as radio, light, and microwaves. The only difference among them is their wavelengths (frequencies). Infrared is our name for electromagnetic radiation with wavelength just longer than red light ... long enough so that our eyes don't respond to it.
What does gamma rays and radio waves have in common?
They are all basically the same thing, electromagnetic radiation, but with different frequencies. All these waves are em waves which travel with the speed of light and it is the common b/w all the waves.
Which travels faster radar or light?
Radar is accomplished by bouncing radio waves from the target.Radio waves and light are the same phenomenon ... both are electromagnetic waves,and their speeds are equal.
