Which wave travels the fastest?
P-wavesSurface waves travel along the surface.
There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids.
Surface waves are the slowest, but they do the most damage in an earthquake..
What are the 7 wavelengths?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Why does energy increase with frequency?
The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Which color wavelengths have the most energy?
Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter – roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
Which type of light travels the fastest?
redViolet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. violet).
Does all light travel at same speed?
Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the “speed of light”; nothing can move faster than the speed of light.
Which is the slower body wave?
The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium.
Why is frequency important in electricity?
Maintaining a consistent electrical frequency is important because multiple frequencies cannot operate alongside each other without damaging equipment. … The exact figure is less important than the need to keep frequency stable across all connected systems. In Great Britain, the grid frequency is 50Hz.
What color is lowest in energy?
RedRed is the lowest energy visible light and violet is the highest.
What color has lowest frequency?
RedRed has the longest wavelength, the shortest frequency, and the lowest energy.
What is the most energetic color?
violetThe color that has the most energy is violet. Since violet waves have the shortest wave length, they carry the most energy.

What is the highest frequency possible?
Gamma-raysThe highest measured frequencies of EM waves are Gamma-rays and are typically produced from the decay of atomic nuclei. The most powerful sources of gamma-rays (and usually the sources with the shortest wavelength) are caused by astronomical events.
Which Colour of light travels fastest in vacuum?
Hence, red will travel the fastest since v=fλ
Which light travels faster red or blue?
Because the number of subquantum energy in a red photon is less than that of a blue photon, red photon interactions are less than the blue photon in the medium. So, the red light travels faster than the blue light.
What is the most dangerous frequency for human body?
30-300 MHzThe most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the human body absorbs RF energy most efficiently when the whole body is exposed.
Which wavelength is the most dangerous?
Ultraviolet (UV) (Wavelength 10-7 – 10-8 meters) The UV portion of the spectrum is subdivided into UV-A, UV-B, and UV-C. UV-C rays are the most harmful and are almost completely absorbed by our atmosphere.
What color has highest frequency?
violetWhen it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
What does the S in S waves stand for?
shear waveAn S wave, or shear wave, is a seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving.
Does higher frequency mean louder sound?
Finding out about frequency Larger vibrations means the sound is louder – called high amplitude – whereas high frequency refers to a higher pitch of sound.
Does higher frequency mean higher power?
Higher frequency does not mean more power. Usually it is more difficult to get high power from a higher frequency laser. … There is no magic photon pump that you can just tune to higher frequency and get the same number of photons per second and hence higher power.
Which Colour is more energetic red or yellow?
Answer. Explanation: coz red can redect energy more than yellow .
What is the weakest EM wave?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Which electromagnetic wave has the most energy?
Gamma raysGamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
Which wavelength has the most energy and why?
gamma raysWe can thus conclude that the waves that have the shortest wavelength are gamma rays, and thus they are the most energetic because they must also have the highest frequency.
Do higher wavelengths have more energy?
What does the length of the wavelength convey? (Short wavelengths have more energy, while long wavelengths have less energy.) 4. UV radiation has a relatively short wavelength, shorter than visible light.
