🌈Vision is enabled through the conversion of light waves into neural impulses in our eyes.
👁️The retina, lined with rods and cones, detects different wavelengths and amplitudes of light waves.
🔴Wavelengths determine the color of what we see, from red to violet, on the electromagnetic spectrum.
⚫️Amplitude impacts brightness and determines the level of detail we perceive.
💡The brain interprets the signals received from the retina to create our visual experience.
How does light become neural impulses in our eyes?
—Light waves enter the eye and pass through the pupil and lens. The retina, which contains specialized cells called rods and cones, detects the light and converts it into electrical signals that are sent to the brain through the optic nerve.
What determines the color we see?
—The color we see depends on the wavelength of the light wave. Different wavelengths appear as different colors, ranging from red to violet, on the electromagnetic spectrum.
What role do rods and cones play in vision?
—Rods and cones are specialized cells in the retina that detect light. Rods are responsible for black and white vision in low light conditions, while cones enable color vision in brighter light.
How does the brain interpret visual information?
—The signals sent from the retina to the brain are processed in the visual cortex, located in the occipital lobe. The brain interprets these signals to create our perception of the visual world.
What is the role of amplitude in vision?
—Amplitude, or the height of a light wave, determines the brightness of what we see. Higher amplitudes result in brighter colors and greater detail, while lower amplitudes appear darker and less detailed.
