What are the colors that make up the visible light spectrum?
Visible light travels at a speed of 300,000 km per second and can be broken down into seven colors. From longest to shortest wavelength, they are: red, orange, yellow, green, blue, indigo, and violet. To be clear, color is the eye’s perception of different wavelengths of electromagnetic light.
Is the light spectrum infinite?
In general the frequency spectrum for Electromagnetic (e.g light, radio, etc) is continuous and thus between any two frequencies there are an uncountable infinity of possible frequencies (just as there are an uncountable number of numbers between 1 and 2).
Which two waves lie at the ends of the visible spectrum?
Based on the electromagnetic spectrum, Infrared and Ultraviolet rays lies at the end of the visible spectrum or visible light.
Does blue or red light travel faster in water?
Red light will travel faster through a dispersive or refractive medium because it is bent less than blue light. Blue light travels slower through glass or water. This is because its shorter wavelength interacts more with the atoms and molecules, and is effectively absorbed and re-radiated.
Why does blue light bend the most?
The bending occurs because light travels more slowly in a denser medium. The amount of refraction increases as the wavelength of light decreases. Shorter wavelengths of light (violet and blue) are slowed more and consequently experience more bending than do the longer wavelengths (orange and red).
Why does blue light travel slower than red light in water?
Does green light has a shorter wavelength than blue light?
Red light has lower frequency, longer wavelength and less energy. Blue light has higher frequency, shorter wavelength and more energy….Visible Spectrum.
| Color | Wavelength Range (nm) |
|---|---|
| Green | 495–570 |
| Blue | 450–495 |
| Violet | 380–450 |
Does green light have a higher frequency than blue light?
Green light has a lower frequency than blue light.
Which color is not a primary color of light?
The color green is what is referred to as a “secondary color”, meaning it is composed of at least two of the primary colors of light. These colors would be yellow and blue, they mix together to produce the color green, which is another specific wavelength on the visible light part of the electromagnetic spectrum.
Which color light has a longer wavelength blue or green?
The visible spectrum
| colour* | wavelength (nm) | energy (eV) |
|---|---|---|
| green | 550 | 2.25 |
| cyan | 500 | 2.48 |
| blue | 450 | 2.75 |
| violet (limit) | 400 | 3.10 |
