very nice answer.
No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).
The light of a wavelength 460nm appears blue to the human eye.
alright, with the given values you have, plug the numbers into this equation: frequency = speed/ wavelength in this case speed is the speed of light 'c' which is 3.0 x 10 ^8 m/s so wavelength = c/f = 300 000 000 (m/s)/ 7.421014Hz = 40425742.36 m = 4.0 x 10^7 m there you go --- gh For your information, purple is not a real colour. It is a combination of red and blue.
wavelengths. Red light has a longer wavelength than blue light, with red light having a wavelength around 620-750 nanometers and blue light around 450-495 nanometers. This difference in wavelength is what gives them their distinct colors.
The visible light with the highest frequency (shortest wavelength) carries the most energy. That means it is the light at the violet end of the 'rainbow'. Since the wavelength of violet light is very roughly half the wavelength of red light, a beam of violet light carries roughly double the energy of a beam of red light with equal intensity. In the particle world, a violet photon has double the energy (and double the momentum) of a red photon. We know from (E=H times nu) that energy is directly proportional to the frequency.
Red has a lower frequency than blue. Blue light has a higher frequency and shorter wavelength compared to red light.
The blue light has longer wavelength, lower frequency, andless energy per photon than the ultraviolet light has.The blue light is also visible to the human eyes, whereas theultraviolet light is not.
colour blue ------> red frequency drops, wavelength increases, because speed remains constant and speed=frequency*wavelength
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.
Wavelength is speed, of light, in this case, divided by frequency. 3 x 108 meters per second divided by 6.82 x 1014 Hertz is 0.4 micrometers.
The color, the frequency, and the wavelength.
The frequency of blue light with a wavelength of 451 nm is approximately 666 THz (terahertz). This can be calculated using the formula: frequency = speed of light / wavelength. In this case, the speed of light is approximately 3.00 x 10^8 m/s.
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
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.
The highest frequency (shortest wavelength) of visible lightis the light at the blue end of the visible spectrum.
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.
wavelength frequency energy are different. speed should be the same.
