objects are visible to us only when?
Objects are visible to us when light from the object enters our eyes and is detected by our retinas. This light stimulates nerve impulses that are sent to the brain, where they are processed and interpreted as images. The visibility of an object also depends on factors such as its size, distance, color, and the amount of available light.
Stars are the only objects in space that give off their own light.Other objects are visible only if a star shines on them.
Only a small piece of the light spectrum is visible to us.
Visible light is the electromagnetic wave that enables us to see objects. It falls within a specific range of wavelengths that our eyes are sensitive to.
Illuminated objects
The term used to describe objects that are visible because of reflected light is "luminous." However, if you're referring specifically to objects that do not emit their own light but are visible due to reflecting light from another source, the term "illuminated" is more appropriate. These objects can be seen only when light from a source, like the sun or a lamp, bounces off them.
The monocular depth cue that states objects blocking other objects are perceived as closer is called occlusion. It helps us perceive depth and distance by interpreting which objects are in front of others based on what is visible to us.
Illuminated objects
An instrument that makes small distant objects visible is a microscope. Microscopes use lenses to magnify tiny objects, allowing us to see details that are not visible to the naked eye. For distant objects, a telescope serves a similar purpose by using lenses or mirrors to magnify and resolve faraway celestial bodies. Both instruments enhance our ability to observe and study the microscopic and astronomical worlds.
No, heat is not visible to the human eye. We can only see objects that emit or reflect light, but heat itself is a form of energy that is detected by our skin or other instruments.
The term used to describe objects that are visible or reflect light is "luminous."
The sun is the only source of light in the solar system. All other visible objects in the solar system are visible only because the sun illuminates them, like a flashlight.
