Red light and blue light both travel at 300 000 000 m/s (300 000 km/s)
They have different wavelengths (and thus different frequencies) with red light having the longest wavelength and smallest frequency.
Blue light carries more energy than red light
Yes. Blue light has a shorter wavelength, and therefore a higher frequency, than red light.
When red light and blue light are both projected onto a white surface, they combine to create magenta light. Magenta light is a different color from red or blue, which is why we don't see red or blue individually in that situation.
Both blue and red light travel at the same speed in a vacuum, which is the speed of light (approximately 3 x 10^8 m/s). However, blue light has a higher frequency and shorter wavelength compared to red light.
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.
A source of blue light would need to emit more photons per second to produce the same amount of energy as a source of red light. This is because blue light has higher energy photons, so fewer photons are needed to achieve the same total energy output as red light, which has lower energy photons.
If your Nintendo 3DS is showing both the red and blue light at the same time, it means you have 2 different notifications. The red light means your battery is low, and the blue light means that you have received a notification.
Red and blue light will not absorb the same light. Red objects reflect red light and absorb other colors, while blue objects reflect blue light and absorb other colors.
Yes. Blue light has a shorter wavelength, and therefore a higher frequency, than red light.
Photographically, both reflect about 50% of the white light falling on them, depending, of course, on their hue. A really dark blue would reflect far less than a light red, same with blue.

On stage in a theatre red light shines and clothes appear red, blue light is shone an clothes appear blue, what colour are they?
Both blue and red light travel at the same speed in a vacuum, which is the speed of light (approximately 3 x 10^8 m/s). However, blue light has a higher frequency and shorter wavelength compared to red light.
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.

Well mixing the colors red and blue give you the color purple....so I will say the same should happen with lights.
No. Light travels at the same speed, regardless of color.
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.
