In a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.

Red light plus blue light equals?
Magenta.
What are the light primary colours?
The primary colors of light, as I studied it, are red, blue and green. The secondary colors are magenta, yellow and cyan. The mixture of all primary colors is white.· Red + Blue = Magenta· Red + Green = Yellow· Blue + Green = Cyan
What are thr three primary colors?
T.T the 3 primary colours for light are: red, blue, green and the 3 primary colours for paint are red, blue, yellow
Compare and contrast the primary and secondary of light and pigment?
primary colors are blue red and yellow when you blend two primary colors together you get secondary colors blue+red=purple red+yellow=orange yellow+blue=green and the primary colors of light are blue red and green. when you mix blue and red light you get magenta, red mixed with green yields yellow. and green mixed with blue yields cyan blue. so you a connection between using pigment and light - the secondary colors of light magenta, yellow and cyan just happen to be the colors that printers use to generate a color picture for you instead of red, blue and green pigment which unfortunately come out too dark to be used in the printing industry. the color mixing of pigments is subtractive and alway generates a color darker than its two parents. but the mixing of colored light is always additive and generates colors brighter than their parents. when you mix all three pigments what do you see black. but when you mix all the colors of light you get white light. see here:http://home.att.net/~B-P.TRUSCIO/COLOR.htm
What are the names of the three primary colors?
To make all colors in pigment the 3 primaries must be transparent. Transparent yellow is ASTM number PY150 made from the nickel element. Transparent magenta is PR122, C20H12N2O2. Transparent yellow and transparent magenta mix into the secondary pigment color red. The 3rd transparent primary pigment color is cyan, made from the copper element, PB15. Transparent yellow and transparent cyan make the secondary color green. Transparent cyan mixed with the the transparent magenta color make the secondary color ultramarine blue. Yellow, magenta and cyan are the primary pigment colors, red, green and blue are the secondary pigment colors. Light uses the opposite colors, the secondary pigment colors become the primary light colors. Red, yellow and blue are not the primary colors in pigment or in light. Those colors came from Newton in 1600 and they are just the most obvious colors in the prism and rainbow. RCW
Why does red light travel faster than blue light in air?
Red light and blue light travel the same speed in a vacuum, however they travel different speeds when traveling through any medium other than a vacuum. In most media, blue light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium and c is the speed of light in a vacuum. Since red has a smaller n than blue in most media, red travels faster then blue in most media. The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium.
In what situation is the speed of waves of red light exactly equal to the speed of blue light?
speed of light is always the same, regardless of frequency/colour.
Does red light travel faster than blue light?
No. All colors travel at the same speed. It is called "the speed of light".
What is white light and how does it travel?
White light is simply a mix of red, green, and blue light. In a vacuum, all light travels at the speed of light (about 300,000 km per second), but it slows down a bit when passing through matter (glass, water, etc.).
Is red light slower than blue light?
No. Light travels at the same speed, regardless of color.
What is white light and how fast does it travel?
White light is simply a mix of red, green, and blue light. In a vacuum, all light travels at the speed of light (about 300,000 km per second), but it slows down a bit when passing through matter (glass, water, etc.).
What if red light is passed through convex lens instead of blue light?
The red light would focus on a point in space at a greater in distance than the blue light would have been. Red light has a longer wavelength than blue light and therefore since both are travailing at the same speed (the speed of light), the longer wave red light finds it's focal point at a time slightly after the blue light would have. This effect shares some characteristics with the Doppler effect, although sound does not need obey the constant speed law as light light does.
What speed does red light travel in space?
In vacuum, such as in space, red light travels at the same speed as a Channel 47 digital color HDTV signal. That speed is 299,792,458 meters per second, or 186,282 miles per second.
What travels faster through the same medium red light or violet light?
Red light and violet light travel at the same speed in a vacuum, however, they travel at different speeds relative to each other when traveling through any medium other than a vacuum.In most media, violet light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium, and c is the speed of light in a vacuum. Since red light has a smaller n than violet light in most media, red light travels faster than violet light in most media.The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium using specific boundary conditions.Read more at the link I provided below.http://wiki.answers.com/Q/Which_travels_faster_red_light_or_violet_light#ixzz17j1yTzi6
Does blue light have a greater speed than red light?
Blue light is diffracted more than red. The way I remember is by thinking about the waves being closer together in the blue light and knowing that each wave interacts with the whatever is causing the diffraction (grating or object). More waves in a given area means more interaction which means more diffraction.
What is the speed of a photon of red light if its frequency is 4.3 x 1014 Hz?
All photons have the same speed in a vacuum, no matter what their frequency. They all travel at the speed of light: 299,792,458 meters per second.
Can blue light be converted to red?
Sure, all you need to do is to travel away from the source at sufficient speed.
