What else can I help you with?
If a red light has a longer wave length than a blue light which one has a greater frequency?
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.
How does blue light differ from red light?
red and blue light differ in wave length because blue lights have shorter wave length than red light and shorter wave length are good for plants germination.
Does ultra-violet light have longer wave-length than visible light?
No.
Is white light in a visable spectrum longer than blue light?
blue light is a part of visible spectra
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.
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"
Does violet have a longer wavelength than blue?
No. Violet has a shorter wavelength than Blue.
Are the wavelengths of light at the red end of the spectrum longer or shorter than those at the blue end?
Longer.
Does red light have a longer wavelength then blue because it's the first colour in the rainbow?
Yes, red light has a longer wavelength than blue light. In the visible light spectrum, red light has a longer wavelength and lower frequency compared to blue light. This difference in wavelength is due to how light waves interact with various materials and how they are diffracted within the atmosphere.
Do x-rays have longer or shorter wave length than visible light?
shorter
Is visible light a shorter or longer wavelength energy in this spectrum?
Shorter or longer than what ? The wavelength of visible light is shorter than that of radio and heat, and longer than the wavelength of X-ray and gamma radiation. And the wavelength of green light is shorter than red light but longer than blue light.
