On stage in a theatre red light shines and clothes appear red, blue light is shone an clothes appear blue, what colour are they?
When light is shined on a cyan object, it will appear cyan as long as the light source contains both blue and green wavelengths, which are the colors that make up cyan. If the light is white, the cyan object will reflect the blue and green light and thus still appear cyan. However, if the light is only red, the cyan object will appear black because it cannot reflect that color.
Photographically, both reflect about 50% of the white light falling on them, depending, of course, on their hue. A really dark blue would reflect far less than a light red, same with blue.
Most objects we know of will reflect both. If you can see an object, its reflecting light. Chances are this same object will bounce sound waves too, no matter how insignificant.A thick, wide mirror will reflect light and probably a good amount of sound.
No, an object cannot be a good absorber and a good reflector at the same time. When an object absorbs light well, it does not reflect much of it, and vice versa. The ability of an object to absorb or reflect light depends on its properties and the material it is made of.
Orange
An object appears a certain color to you because it reflects that color of light and absorbs other colors of light. For example, a white object appears white because it reflects all colors of visible light (red, orange, yellow, green, blue, indigo, violet). A black object appears black because it absorbs all of these colors--and as a result, none of those colors are reflected back to your eyes. Under white light, the object appears yellow-green because it reflects both yellow and green light and absorbs all other colors. (Remember, white light has all colors of visible light in it). If only green light is present, there's only green light for it to reflect--so it will appear green. If you shined yellow light on it only, it would be yellow. If you shined yellow and green light, it would appear yellow-green again. It you shined red and blue light on it, it would appear black, because it absorbs both of those colors.
Both mercury the metal and Mercury the planet reflect light quite well.
Water can both refract and reflect light. When light travels from one medium to another in water, it bends due to the change in speed, which is known as refraction. Additionally, light can also reflect off the surface of water, creating a reflection.
Mirrors and lenses are both optical devices that manipulate the path of light. Mirrors reflect light by bouncing it off their surface, while lenses refract light by bending it as it passes through. Both can be used to form images and magnify objects.
TRUEEEEEEEEEEEEEEEEEEEE!:]
Light can both go through and reflect off of glass. When light passes through glass, it is transmitting through the material. However, if the angle of incidence is steep, light can reflect off the surface of the glass.
They both reflect light.
