The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest 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
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.
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.
Assuming you mean visible light, that would be red light.
Red has the longest wavelength, up to 750nm.
very nice answer.
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.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Its frequency (wavelength).
Because red light has minimum frequency and thus it has maximum wavelength.
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
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 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.
-- 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.
Its frequency (wavelength).
Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of microwaves. Infrared radiation has wavelengths between about 750 nm and 1 mm. To convert wavelength to frequency, divide the speed of light by the wavelength. Speed of light is 300000000 m/s so 1mm corresponds to a frequency of 3E11 or 300GHz 750nm corresponds to a frequency of 4E14 or 400THz if I didn't drop a decimal point somewhere.
