It is 90 degrees more than the original angle.
Yes, by 30 degrees.
An angle which is more than 180 degrees but less than 360 degrees is called a reflex angle.
An angle that measures more than 90 degrees and les than 180 degrees is an obtuse angle.
How many degrees in what? Your question needs more information.
The sun does because it's light reflects off the moon. The more light reflected the bigger the shape. The less light reflected, the smaller the shape.
More or less the same as when the light falls anywhere else. Part of the light will be reflected, part of it will be absorbed. Light will usually not pass through a can, which is not transparent for visible light.
The amount of light reflected by an object's surface is affected by its texture, color, and reflective properties. Smooth and brightly colored surfaces tend to reflect more light, while rough or dark surfaces may absorb or scatter more light. The angle of incident light can also impact the amount of light reflected.
When light hits a painted door, some of the light is absorbed by the paint, and some is reflected. The color of the paint determines which wavelengths are absorbed and which are reflected, giving the door its color appearance. If the paint is glossy, more light will be reflected, creating a shinier appearance.
The term is "albedo," which is a measure of the reflectivity of a surface or body, indicating how much incoming light is reflected back. A high albedo means more light is reflected, while a low albedo means more light is absorbed.
The amount of light reflected by an object depends on the surface properties of that object, such as its texture, color, and reflectivity. Objects that are smooth and shiny tend to reflect more light, while objects that are rough and matte tend to absorb more light.
Blue light, with a wavelength around 450-495 nm, is predominantly reflected from the surface of ocean water. This is why the ocean often appears blue as it reflects this wavelength of light more efficiently than others.
More or less yes, basically the red paint absorbs all of the colours of light except for the red light which is reflected. It is this reflected red light which we see.
When you see color, it is because certain wavelengths of light are being reflected by the object and other wavelengths are being absorbed. The colors we perceive are based on which wavelengths of light are reflected back to our eyes.
The measurement of how well a substance reflects light is called reflectance. It quantifies the amount of light that is reflected off a surface compared to the total amount of light that hits it. High reflectance means more light is reflected, while low reflectance means more light is absorbed or transmitted.
Some light that falls on any surface is scattered back (reflected). A rough surface tends to scatter the light in different directions while a smooth surface tends to scatter more of the original (incident) rays straight back. This explains why a smooth surface reflects a "clearer" image than that reflected from a rough surface.
