What is near far focal point?
The near and far focal points refer to distances at which light rays are brought into focus by a lens or mirror. The near focal point is where light rays converge when the object is closer than the focal length. The far focal point is where light rays converge when the object is beyond the focal length.
Can light be reflected off water?
Yes. Everything you see is the light reflecting off of the object you see. So when you see yourself in water that the light bouncing off your face onto the water and back to your eyes.
What would a green object look like in a magenta light?
A pure green object would reflect the green third of the spectrum, and absorb the red and blue portions. Magenta light is composed of red and blue waves so they would be absorbed by the green object. Therefore, in theory, a green object would appear neutral, virtually black. But this assumes that all the colors are very pure and perfectly balanced. This is unlikely, so the object would most likely look near neutral with some color skewing one way or another.
How does infrared light reflect off objects?
Infrared radiation or light is part of the electromagnetic spectrum and acts the same as visible light does.Infrared can be absorbed and reflected by objects much the same way as visible light. More on Infrared:Some black objects that absorb visible light radiation may reflect infrared.Much of the absorbed visible light energy is re-emitted as infrared up to many hours later.There are subcategories of infrared, two common ones are near-infrared and far-infrared. Near being closer to visible light.
When an object is placed near a screen why is there no image formed?
This is due to the way that light rays bend. When the image is close to the screen, the light rays reflect off the mirror and do not converge or diverge. Rather than travel perpendicular to each other, the light rays travel parallel?æto each other. This does not allow an image to form.
What three things can happen to a light wave when it strikes an object?
Light striking an object can be reflected, refracted, or absorbed. Light passing near an object can be diffracted. These are all the possible interactions.
When an object casts 2 shadows?
When there is two light soucres near the object
What causes the light from far away galaxies to bend?
If the light from a distance galaxy passes near a massive cosmic object, then the gravity of that object will distort space-time. That will cause the light to bend.
Is putting an object near the light source making it big?
you can't make an object bigger with light, you can make the shadow bigger by moving it closer to the light source because there is more surface area to block the light.
What is near far focal point?
The near and far focal points refer to distances at which light rays are brought into focus by a lens or mirror. The near focal point is where light rays converge when the object is closer than the focal length. The far focal point is where light rays converge when the object is beyond the focal length.
How celestial masses effect the passage of light?
According to the General Theory of Relativity, the path of light is bent near large masses. The more massive a celestial object is the more light is bent near it.
Can light be reflected off water?
Yes. Everything you see is the light reflecting off of the object you see. So when you see yourself in water that the light bouncing off your face onto the water and back to your eyes.

Why does black absorb sunlight?
Black absorbs sunlight because it contains pigments that absorb a wide range of wavelengths of light, including those in the visible and near-infrared spectrum. This absorbed light energy is then converted into heat, which raises the temperature of the black object.
What does the lens in an eye do?
Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens. The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.
