Since the energy of a photon is directly proportional to the frequency of the light, the light having the greatest frequency will have the greatest energy per photon. Therefore, the violet light will have the greatest energy per photon.
Which Colour photon is more energetic red or violet give reason?
The wavelength of violet light is smaller than red light. Hence, the frequency of violet is larger than the red one. So, the violet photon is more energetic than the red one.
Which Colour photon is more energetic red or blue give reason?
The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more. Red photons, for example, have less energy than blue ones. More energetic wavelengths such as blue and ultraviolet caused more electrons to be ejected than red or infrared wavelengths.
Which photon is more energetic yellow or red?
coz red can redect energy more than yellow .
What color has less energy per photon?
There are electromagnetic waves of longer wavelength and lower frequencies than red light, and they have lower energies per photon than red light, but we are not able to detect them with our eyes.
Is violet more energetic than red?
We know the fact that energy of photon is inversely proportional to the wavelength and in contrast red light have high wavelength than Violet. so Violet is more energetic.
Which light has most energy?
Gamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
Which light will give more energetic photoelectrons *?
Since frequency of violet light is more than that of red light, i.e., vviolet>vred and energy of a photon = hv. So photon of violet light is more energetic than that of red light.
Which light Colour has maximum energy?
In our case of visible light, the highest frequency color, which is violet, which means it will have the highest energy.
Which photon is more energetic red or green?
, that is, energy of a photon is inversely proportional to the light’s wavelength. – Hence, the light having the lowest wavelength will have maximum energy. – On the basis of wavelength, red has the maximum wavelength, then green, then comes blue and lastly violet. Therefore, violet has the maximum energy.
Which type of wave travels the fastest?
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
Is red light more energetic?
Visible Spectrum Visible Light: the wavelengths that are visible to most human eyes. Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy. Blue light has higher frequency, shorter wavelength and more energy.
What color is lowest in energy?
Red is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.
What light has lowest energy per photon?
Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.
What color travels the fastest?
Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top.
Which is more energetic radiation?
Gamma rays are the most energetic form of electromagnetic radiation.
What is the highest energy?
A collaboration of Chinese and Japanese astrophysicists has reported the highest energy photons ever seen: gamma rays with energies up to 450 trillion electron volts (TeV).
Which is the highest frequency?
Gamma rays have the highest frequency in the electromagnetic spectrum. They have a frequency of the order of about 1020 to 1022 Hz.
What color is the lowest frequency?
The visible spectrum of light has frequencies ranging from 400−790THz. We can see that the colour Orange has the lowest frequency among the choices given.
What color has the highest frequency?
Violet waves have the highest frequencies.
Which color of light has the shortest wavelength?
We see these variations as colors. On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum.
Which color has the most energy Activity 4?
1. energy of the colors of light increases as one goes towards the right side of the color spectrum. 2. red light has the least energy and blue light has the most energy.
What is the most energetic color?
When 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.
Which type of wave has the longest period?
Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Which photon carries the most energy blue?
Ultraviolet radiation has shorter waves than blue or violet light, and thus oscillates more rapidly and carries more energy per photon than visible light does. Light travels at a speed of 299,792 kilometers per second (about 186,282 miles per second).
Which Colour has highest velocity in air?
The colour violet travels the slowest, so it is on the bottom and the colour red travels the fastest so it is on the top.
Where do P-waves travel the fastest?
P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them.
Which of the 4 types of waves travel the fastest?
1. Mechanical waves- travel faster in solids & slowest in gases 2. Electromagnetic waves- travel fastest in empty space and slowest in solids. 4.
Where do P-waves travel?
In a P wave, the rock particles are alternately squished together and pulled apart (called compressions and dilatations), so P waves are also called compressional waves. These waves can travel through solids, liquids, and gases. P waves can travel through the liquid outer core.
Does red light travel faster than blue?
In air, glass, water and many other transparent materials, red light travels faster than blue light.
What is the frequency of red light in Hz?
Wavelengths of light range from about 400 nm at the violet end of the spectrum to 700 nm at the red end (see table).The visible spectrum. colour* red wavelength (nm) 650 frequency (10 14 Hz) 4.62 energy (eV) 1.91.
Why does red light travel faster in glass?
Therefore, by the refractive index formula, the wavelength of light is directly proportional the speed of light in the medium. Therefore, the speed of red light will be greater than the violet. Therefore, in glass the red light will travel faster than the violet light.
