how do we see color wavelength
The light waves reflect off the bananas peel and hit. Color is determined first by frequency.

The light first passes through a tough protective sheet called the cornea and then moves into the lens.
. Violet has the shortest wavelength at around 380 nanometers and red has the. LCD arrays and B. Each color has a different wavelength.
Only the colors that bounce off reach your eyes. When all the waves are seen together they make white light. Some of the waves are longer.
The largest number of photoreceptors in the eye. Refraction experiments show it is the frequency that determines color. Violet has the shortest wavelength and the highest frequency and energy.
The wavelengths that dont bounce off get absorbed as heat. The color we see is a result of which wavelengths are reflected back to our eyes. How do we see color.
Red has the longest wavelength. These spectral colors do not refer to a single wavelength but rather to a set of wavelengths. The order of colors in light arranged from shortest wavelength to longest is called the visible spectrum of light.
The image below shows lights visible spectrum which runs from violet to red. The blue side reflects blue light. Furthermore how do we see light.
The eye doesnt perceive violet so well. λ 1 v 1 f. Figure 5 - A.
When a beam of light crosses the boundary between two medium whose refraction index are n 1 n 2 its speed changes v 1 c n 1. One that looks red one that looks green and one that looks blue. The SPD provides the basic physical data needed to calculate light source color.
When you look at a banana the wavelengths of reflected light determine what color you see. You might recognize the spectrum as the order of colors in a rainbow. We see the waves as the colors of the rainbow.
Humans see the world differently than most other animals. As the frequency is increased the perceived color gradually changes from red to orange to yellow to green to blue to violet. We see the waves as the colors of the rainbow.
This overlap along with the brain processing the simultaneous signals sent to it actually allows us to see millions of colors. 1 Angstrom 10 -10 meters. For example the color yellow results from green and red cones being stimulated together while the blue cones need no stimulation other than the one blue wavelength.
Violet has the shortest wavelength. Each color has a different wavelength. For example Figure 2 shows the SPD of an incandescent lamp.
The yellow side reflects yellow light. Red has the longest wavelength. V 2 c n 2 its frequency does not change because it is fixed by the emitter so its wavelength changes.
The yellow side reflects yellow light. Light travels into the eye to the retina located on the back of the eye. Light comes to Earth from the sun in waves.
Some of the waves are shorter. The spectral power distribution SPD of a light source is graphical or tabulated data representing the amount of radiation emitted by a light source at each wavelength in the visible spectrum only. These unique wavelengths determine the shades and hues of the colors we see.
We see them as colors of the rainbow. Red has the longest wavelength the shortest frequency and the lowest energy. These unique wavelengths determine the shades and hues of the colors we see.
The color of light coming from an object is what gives it color. Light goes through your eyeball much larger than the nano-meter scale wavelengths of visible light before it hits the retina. Now go and look at your screen through a magnifying glass or more conveniently look at Figure 5A and you will see that there are only three types of light in any color video screen.
