The reason the wall appears black is that it absorbs light in the visible spectrum (~400nm to ~700 nm in wavelength); otherwise, the wall is no longer black. A green wall reflects green light (~500 nm) but absorbs all else.
===========================
When light waves strike a blue object, the object absorbs most of the colors in the light spectrum except for blue. Blue light waves are reflected off the object, giving it its blue color.
When objects reflect all light waves that strike them, they will appear white. This is because when all colors of light are reflected equally, they combine to create white light. On the other hand, a black object absorbs all light waves that strike it, so it appears black as no light is being reflected back.
When waves and light strike a surface, they can be reflected, absorbed, or transmitted. Reflection occurs when the waves bounce off the surface, absorption happens when the waves are taken in by the material, and transmission is when the waves pass through the surface.
im assuming that u meant "what happens when LIGHT hits a black surface?" the reason for this is that the black surface ABSORBS the light, and so none of the light waves can be reflected back (which is what makes it look black)
That means that the light waves rebound, and change direction.
No, not all light waves that strike a convex lens pass through the focal point. Light waves that are parallel to the principal axis will pass through the focal point after refraction, while light waves that strike the lens at different angles will converge at different points along the focal plane.
Depending on the material and its properties, light waves can be absorbed, reflected, or transmitted when they strike an object. The specific outcome is determined by factors such as the object's color, texture, density, and transparency.
light waves or electromagnetic waves are transverse and sound waves are longitudinal
Diffuse reflection occurs when parallel light waves strike a rough or uneven surface. This type of reflection scatters the light waves in different directions, resulting in a soft and non-specular reflection of light. Examples of diffuse reflection include light bouncing off surfaces like paper, fabric, or matte paint.
No. A black hole does not reflect light waves. But that is assuming you regard a black hole as an "object."
As you know that there are three types of light waves i.e infrared light, visible light and ultra violet light. Out of these, only visible light rays (waves) gets reflected by the mirror but the other two light waves passes through the mirror.
They refract
