Red light waves and blue light waves travel at the same speed in a vacuum, which is the speed of light (about 299,792 km/s). The perception that red light travels faster could be due to differences in how the human eye perceives the colors or how the waves interact with materials.

Does red light travel faster than blue light?

No. All colors travel at the same speed. It is called "the speed of light".


When light waves strike a blue object what happens to the light waves of all colors?

When light waves strike a blue object, the object absorbs most of the colors in the light spectrum except for blue. Blue light waves are reflected off the object, giving it its blue color.


Give two differences between red yellow and blue light waves?

they travel at a different frequency.


In the light spectrum are red waves shorter than blue waves?

Red light waves are almost double the length of blue or violet light waves. Wavelength is inversely proportional to frequency; red light has a higher frequency than blue light.


What is energy of blue light waves compared to red light?

Blue light waves have higher energy compared to red light waves because blue light has a shorter wavelength. This means that blue light photons have greater energy levels than red light photons.

Which color of light, red or blue, travels faster in crown glass?

Blue light travels faster in crown glass compared to red light.


Why do plants grow faster in blue light?

it grows faster


Why do plants grow faster under blue light?

because blue light has a lot of energy so the plant grows faster


What light waves does a blue object reflect?

The wavelengths are corresponded to the color of the light. A blue object will reflect any light radiation expect the color blue. It will absorb the blue light.


Which have longer wavelength radio waves or light waves?

Radio waves have a far longer wavelength than visible light. The radio waves that do the cooking in your microwave oven are as long as roughly 310,000 waves of blue light placed end-to-end. The radio waves transmitted by an AM station at 1400kHz on your AM dial are roughly 550 billion times as long as blue-light waves.


Why do the physics books tell us that red lights travels faster than blue light when they're all electromagnetic waves?

No physics book published since 1920 should have said such a thing. Electromagnetic waves all travel at the speed of light in the medium they transit. In a perfect vacuum all travel at "c". But they do change frequency IN ORDER TO MAINTAIN their velocity, since the wave numbers are maintained. As an example-- a source of light coming toward you will be bluer, and one receding from you will look redder. But the velocity will be "c" in a vacuum.
