The human eye sees red when it looks at light with a wavelength between 630 and 700 nanometers.
the shortest of all rays
Their product is always the speed of the sound.
Wavlength
Wavelength is a length. The SI unit for length is the meter (m).
when someone discovers which came first: the egg or the chiken
Wavelength is the distance between one crest (top) of a wave to the next crest. It is like measuring how long one wave is from start to finish. Shorter wavelengths have higher energy and frequency, while longer wavelengths have lower energy and frequency.
No, the wavelength of the wave does not change when it undergoes refraction as it moves from one material to another. The frequency remains constant, and only the speed and direction of the wave change.
All of the frequencies of the visible spectrum, or about 430-790 THz. Red light has a wavelength of about 700 nanometers and violet light has a shorter wavelength about 400 nanoes and so we can see those colours and anything in between like green and yellow. When the wavelength is a bit too short to be seen we call it ultra-violet, and wavelengths a bit too long we call infra-red. This answer talks about wavelengths while the question asks about frequencies. Sorry, but its easier for me to talk about wavelengths. To answer the question fully, wavelengths can be turned into frequencies by dividing the speed of light (30,000,000 metres per second) by the wavlength. That makes a wavelength of 400 nanoes into a frequency of 30,000,000 / 0.0000004 = 75,000,000,000,000 cycles per second (Hertz). 700 nano red light has a frequency of about 43,000,000,000,0000 Hertz.
Unfortunately there is NO working cheat for it as of yet. All the listed cheats for that costume have proven to be utterly false. So, as of yet, the only way to actually get it is to complete all 180 Challenges.
Red + Red = Red Red + Blue = Purple
Its red red red
because red Redd's red is reddy red red.
