Many find the pnemonic ROY G BIV helpful.
It represents Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
Red has the lowest frequency, and Violet has the highest frequency.
Therefore, blue light is more energetic, representing a frequency of about 6.38*1014 Hz (470nm).
Yellow light has a frequency of about 5.17*1014 Hz (580nm).
So blue light has a higher frequency than yellow light.
Blue. See this link: http://www.lbl.gov/MicroWorlds/ALSTool/EMSpec/EMSpec2.html Hope this helps!
Ultraviolet
Blue light is of a higher energy than red light. That means that the fire with the blue light is hotter, as the fire must generally be hotter to generate the blue light. For example, in a gas flame, the blue, which is hottest, is in the middle, and any yellow, orange or red is around the outside.
Has a different wavelength and energy. At the red end of the spectrum the wavelength is longer and frequency is lower, it will be less easily refracted than light towards the blue end of the spectrum, which is higher in frequency and has a shorter wavelength. The separation of the colours is called dispersion.
The colour of an object is determined by the wavelengths of light it reflects. An object that is purley one wavelength (lets say a specific wavelength in the blue part of the spectrum) would be absorbing all visable wavelengths except that specific blue wavelength.
Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.
Xanthophylls primarily absorb green-blue light.
Yellow light has the lower frequency.
Indigo has a higher frequency..
Yes. Blue light has a lower wavelength than yellow light, which is why it is perceived by out eyes as a different color. Blue light's wavelength is around 450 nanometers and yellow light's wavelength is around 575 nanometers. since the speed of light is constant for all light, and frequency is the speed of light over the wavelength of the light, the larger the wavelength, the lower the frequency. And the lower the frequency, the lower the energy. So the shorter wavelength of light (in this case, blue colored light) has a faster frequency, and therefore more energy.
Yes. Blue light has a shorter wavelength, and therefore a higher frequency, than red light.
Green light. If you use the abbreviation ROY G. Biv ( red, orange yellow, green, blue, indigo, violet), you will always know that the red light has the longest wavelength and violet has the smallest wavelength. Wavelength and frequency are inversely proportional to one another. So if the wavelength is large, frequency is small, and when wavelength is small, frequency is large. Green light has a smaller wavelength than yellow. Likewise it has a higher frequency than yellow does. Therefore, green light has a higher frequency than yellow light.
In the spectrum of electromagnetic radiation the wave property that changes is the frequency. So for example xrays have higher frequency then blue light which has higher frequency then red light which has higher frequency then radio waves etc.
Red light waves are almost double the length of blue or violet light waves. Wavelength is inversely proportional to frequency; red light has a higher frequency than blue light.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
infrared light:)
Yes. Blue has higher frequency than yellow. As per quantum theory the energy content of photon is directly proportional to the frequency and so blue has high energy concentration.
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack
From the items on that list, infrared light has the lowest frequency, and X-rays have the highest.
