The color of the wavelength lambda = 595 nanometers is "orange-yellow" and not blue. The wavelength lambda = 595 nanometers equals the frequency f = 503,852,870,588,235 Hz. Blue light is between 490 and 450 nonometers. 1 nanometer = 1×10−9 meter. 595 nm = 0.000000595 meters. Scroll down to related links and look at "Radio and light waves in a vacuum".

Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
How would the wavelength and frequency of a red light compare to the wavelengths and frequencies of green and violet lights?
-- Red light has the lowest frequency of those three. -- Green light has lower frequency than violet light has. -- The wavelength of all light is inversely proportional to its frequency.
Why is frequency of red greater than violet?
The wavelength of violet light is shorter.
Why won't a very bright beam of red light impart more energy to an electron than a feeble beam of violet light?
Ok, so this goes back to the inverse relationship between wavelength and frequency ( energy). As wavelength increases , frequency decreases, the relationship between the two is a inverse relationship. the Red light, wavelength of approx. 700 m^-7 , has a greater wavelength then of the blue light, 400m ^-7. This means , due to frequency and wavelength having an inverse relationship, blue light has a greater frequency (energy) than red light. This is why blue light, no matter how dim, will impart more energy to an electron , then a red light would.
What is the relationship between the color of light and its wavelength?
Each color has a wavelength and frequency associated with it. We're familiar with the colors of the rainbow: red, orange, yellow, green, blue and violet. These colors range from longer wavelength (lower frequency) red up through shorter wavelength (higher frequency) violet. As one moves up through those colors from red to violet, the color is an indication to relative wavelength.
How do the wavelength and frequency of red light compare to the wavelength and frequency of blue light?
very nice answer.
Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
Which light has the longest wavelength and the shortest frequency?
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
What makes a red light appear red?
Its frequency (wavelength).
Why is red light having maximum wavelength?
Because red light has minimum frequency and thus it has maximum wavelength.
Between green light and red light which has a higher frequency?
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
True or false visibe light with the shortest wavelength is red light?
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).
How do the wavelength and frequency of an X-ray compare with those of the red light from a neon sign?
The wavelength of an X-ray is much shorter than the wavelength of a red light from a neon sign. The frequency is much longer in an X-ray than the frequency of a red light from a neon sign.
How would the wavelength and frequency of a red light compare to the wavelengths and frequencies of green and violet lights?
-- Red light has the lowest frequency of those three. -- Green light has lower frequency than violet light has. -- The wavelength of all light is inversely proportional to its frequency.
What makes a light appear red or green?
Its frequency (wavelength).
What is the difference between blue light and green light?
In the visible region of electromagnetic spectrum VIBGYOR, violet having highest frequency is at one extreme and red having the lowest frequency goes to other extreme. So violet with shortest wavelength and red with the longest.
Which wavelength of light has the lowest frequency?
Assuming you mean visible light, that would be red light.
