When a photon reaches the retina it MAY energize an electron in a protein (such as keratin), this change can be detected by certain cells which will then send a signal (chemical - see neuro-transmitters) to nerve cells which make up the optic nerve.
The human eye can perceive light wavelengths ranging from approximately 380 nanometers (nm) to about 750 nm. This range encompasses the visible spectrum, which includes colors from violet (shorter wavelengths) to red (longer wavelengths). Beyond this range, ultraviolet light (below 380 nm) and infrared light (above 750 nm) are not visible to the human eye.
This is a difficult question to answer, as the brightness of light is itself perceived, rather than actual. In some ways, light is brighter than you can perceive it, simply because another person can perceive that light to be brighter than you yourself perceived it. The brightness of light to the eye is relative.
Your eye would perceive the light as yellow because each color corresponds to a specific wavelength of light that is detected by different color receptors in your eyes.
The human eye is most sensitive to green light and can see it the best compared to other colors. This is why many night vision devices use green light to help improve visibility in low-light conditions.
No, gamma rays are not visible to the human eye.
Cones perceive color in the human eye.
Yes, there are colors that are invisible to the human eye, such as ultraviolet and infrared light. These colors fall outside the visible spectrum of light that our eyes can perceive.
The human eye can perceive approximately 10 million different colors.
Visible light energy is the type of energy that is detectable by the human eye. It falls within a specific range of wavelengths in the electromagnetic spectrum that our eyes can perceive as colors.
You can perceive ten images per second by your eye. That is the reason, why you have ten images per second in case of the motion pictures. In that case you perceive that the object is in continuous motion. The human eye can see electromagnetic radiation in the frequency range 430-790 Terahertz, corresponding to colours from red to violet.
The human eye has three kinds of color receptors, which perceive red, yellow, and blue wavelengths of light. If you perceive red and yellow simultaneously, that is interpreted as orange.
The self-light of the eye refers to the idea that the eye is able to perceive light and objects without needing external light sources. This concept is significant in understanding human perception and consciousness because it suggests that our ability to see and perceive the world is not solely dependent on external stimuli. It implies that there is an internal mechanism within us that allows for perception and consciousness to occur, highlighting the complex and intricate nature of human cognition.
The human eye can perceive about 20 stops of dynamic range.
VIsual light
No, humans cannot perceive ultraviolet light with the naked eye. Our eyes are sensitive to the visible light spectrum (400-700nm) and cannot detect ultraviolet light which has shorter wavelengths.
The human eye has different amounts of pigment in each retina, causing one eye to perceive more blue light than the other.
Yes, the human eye can detect light of different wavelengths. This is because the eye contains different types of photoreceptor cells - cones for color vision and rods for low-light vision. Each type of photoreceptor is sensitive to a specific range of wavelengths, allowing the eye to perceive a wide spectrum of colors.
