What are the different speeds of the electromagnetic spectrum?
In terms of speed, every part of the electromagnetic spectrum, (radio waves, infra-red, ultraviolet), all travel at the same speed in a vacuum, the speed of light, which is 300,000,000 m/s approx. In terms of energy, the low frequency and long wavelength end of the spectrum, such as radio, have a low energy as opposed to the high frequency and short wavelength end, such as gamma rays.
Which region of the em spectrum will travel with the fastest speed?
All regions of the electromagnetic spectrum travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. So, they all travel at the same speed, regardless of their wavelength or frequency.
What are facts about visible light?
Light is a form of electromagnetic energy. Visible light ranges through all the colors of the rainbow - red, orange, yellow, green, blue and violet. Light is generally considered to be those wavelengths and also some wavelengths just below red (infrared or IR) and just above violet (ultraviolet or UV). Light has an energy associated with it, and the lowest energy light is at what is called the lower end of the spectrum, which is the red end. The higher energy light is at the higher end of the visible spectrum, the purple (or violet) end. Higher energy light has a higher frequency and a shorter wavelength than lower energy, which has a lower frequency and a longer wavelength. Light, because it is electromagnetic energy, is different from mechanical energy, like sound (which is mechanical energy). Light can travel through a vacuum. The speed of light in a vacuum is a constant, no matter what frame of reference the observer has, and that is exactly 299,792,458 meters per second (about 186,282.397 miles per second). A link is provided to the Wikipedia article on light in case you wish to do some additional reading. And there is always WikiAnswers for more questions.It is part of the electromagnetic spectrum.It has the characteristics of a wave and a particle.The photon is the force carrier.It travels about 300,000 kilometers per second.It can be refracted, reflected or absorbed.It's energy is used in photosynthesis and in our eyes.It has pressure, this can be increased to make lasers, etc.The SI unit of measure is the candela.
Do gamma rays travel the speed of light?
Yes, gamma rays travel at the speed of light, which is approximately 299,792 kilometers per second in a vacuum. This is because gamma rays are a form of electromagnetic radiation, like visible light and radio waves, and all forms of electromagnetic radiation travel at the speed of light in a vacuum.
What is hertz in light?
In the context of light, hertz (Hz) refers to the frequency of light waves, which is the number of complete wave cycles that pass a given point per second. Higher frequencies in the visible spectrum correspond to colors with shorter wavelengths, such as violet light, while lower frequencies correspond to colors with longer wavelengths, like red light.
The electromagnetic spectrum is made up of?
Electromagnetic spectrum is made up of wide range of frequencies which range from few Hertz (cycles per second) to several TeraHertz. In most books, electromagnetic spectrum is marked with help of wavelengths. Wavelength is measured by speed of light divided by the frequency.
Which of theses two beams is most likely in the ultraviolet region of the electromagnetic spectrum?
I'll say the second one is. (The one on the right.)
What on the general electromagnetic spectrum has the second largest wavelength?
Microwaves
What has the second longest wavelength?
Red light has the second longest wavelength in the visible light spectrum, after infrared light.
How is frequency defined in electromagnetic energy?
in electromagnetic spectrum, the number of waves that pass a certain point in one second is the wave's what
What is the relationship between wave length and energy on the electromagnetic spectrum?
The relationship between electromagnetic energy (photon energy) and wavelength is determined by two constants - the speed of light and Planck's constant. Photon energy (in Joules) is equal to the speed of light (in metres per second) multiplied by Plancks constant (in Joule-seconds) divided by the wavelength (in metres). E = hc/wavelength where: E is photon energy h is Planck's constant = 6.626 x 10-34 Js c is the speed of light = 2.998 x 108 m/s This relationship shows that short wavelengths (e.g. X-rays) have high photon energies while long wavelengths (e.g. Radio waves) have low photon energies.
What is eletromagnetic spectrum?
The electromagnetic spectrum is the full range of known electromagnetic radiation, ranging from radio waves to gamma rays. Radio waves are at one end of the spectrum with the longest wavelength and the lowest frequency. Gamma rays at the other end have the shortest wavelength and the highest frequency. (frequency = wave oscillations per second) Most electromagnetic radiation can fall into one of the following categories: Radiowave Microwave Infrared Visible (light) Ultraviolet X-rays Gamma Rays [This list is in increasing order of frequency)
What are the different speeds of the electromagnetic spectrum?
In terms of speed, every part of the electromagnetic spectrum, (radio waves, infra-red, ultraviolet), all travel at the same speed in a vacuum, the speed of light, which is 300,000,000 m/s approx. In terms of energy, the low frequency and long wavelength end of the spectrum, such as radio, have a low energy as opposed to the high frequency and short wavelength end, such as gamma rays.
What color of the spectrum has the second shortest wavelength?
According to (longest wavelength) ROYGBIV (shortest wavelength), it would be "indigo."
All electromagnetic waves travel at speeds of?
All waves in the electromagnetic spectrum travel at 3x108 ms-1 or 300000000 metres every second.
What is the second longest wavelength in the absorption spectrum of hydrogen?
The second longest wavelength in the absorption spectrum of hydrogen corresponds to the transition from the n=2 to n=4 energy levels. This transition produces a spectral line known as the H-alpha line, which falls in the red part of the visible spectrum at a wavelength of 656.3 nm.
How fast do electromagnetic travel?
Electromagnetic waves travel at the speed of light in a vacuum, which is approximately 186,282 miles per second (299,792 kilometers per second). This speed is constant in a vacuum and the fastest speed possible in the universe.
