Why is red light different to blue light?
The red light is lower energy than the blue light.
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.
Does blue or red have a higher frequency?
Blue light has a higher frequency than red light. When we see different colors, we are actually perceiving different wavelengths of light - blue light has a shorter wavelength and higher frequency than red light.
Does blue light have travel at a different frequency than red light in the same medium?
Yes. Blue light has a shorter wavelength, and therefore a higher frequency, than red light.
Does red light have a longer wave length than blue light?
Red Light
How does focal length of convex lens change if monochromatic red light is used instead of monochromatic blue light?
Blue light travels slower in glass then red and so has a higher index of refraction. That results in a shorter focal length. Search Chromatic aberration in Wikipedia.org, "The World's Encyclopedia"
What is the lowest frequency blue or red?
Red has a lower frequency than blue. Blue light has a higher frequency and shorter wavelength compared to red light.
What color does blue light and red light make?
Blue light and red light do not combine to form a new color because they are on opposite ends of the visible light spectrum. Blue light has a shorter wavelength and higher energy than red light. When the two colors are combined, they may appear as a mix of blue and red rather than creating a new color.
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.
Does blue light scatter less than red light?
Blue light scatters more than red light. This is because blue light has a shorter wavelength, causing it to interact more with particles in the atmosphere, like air molecules and dust, which leads to more scattering.
Does red light has a longer wavelength than blue light?
Yes, red light has a longer wavelength than blue light. Red light has a wavelength between approximately 620-750 nanometers, while blue light has a wavelength between approximately 450-495 nanometers.
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.
