A blue object appears black when illuminated with light because it absorbs most of the light that hits it, including the blue light that gives it its color. This absorption of light prevents the object from reflecting enough light to appear blue, making it appear black instead.

In which of these cases will a ripe banana appear black when illuminated with red yellow green or blue light?
A ripe banana will appear black when illuminated with red, green, or blue light, as these colors are absorbed by the banana's pigment. Only yellow light will be reflected, making the banana appear black under the other colors of light.
How can light make a red object look black?
When a red object is illuminated by red light, it can absorb all the red wavelengths and appear black, as there is no red light to reflect and the object appears dark. This phenomenon is called color subtraction.
What is an example of an illuminated object?
An example of an illuminated object is a light bulb. When turned on, a light bulb emits light, making it an illuminated object.
A sheet of red paper will look black when illuminated with what light?
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.
Explain briefly why an object which appears yellow in daylight appears red when illuminated with red light and red when illuminated with magenta light?
The color of an object depends on the wavelengths of light that it reflects. When an object appears yellow in daylight, it reflects mostly yellow light. When illuminated with red light, which contains only red wavelengths, the object reflects primarily red light, making it appear red. When illuminated with magenta light, which contains red and blue wavelengths, the object absorbs the blue light and reflects only the red, appearing red.
What color will a yellow banana appear to be when illuminated by blue light?
Black

Why the shadow is black in colour?
Shadows appear black because they are formed when an object blocks light, preventing it from reaching the surface behind it. Since light cannot pass through the object, the area behind it appears dark in comparison to the surrounding illuminated areas.
If A green leaf placed in a dark room is illuminated by red light the leaf will appear to be?
black
A sheet of red paper will look black when illuminated with what light?
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.

The color of an object depends on the wavelengths of light that it reflects. When an object appears yellow in daylight, it reflects mostly yellow light. When illuminated with red light, which contains only red wavelengths, the object reflects primarily red light, making it appear red. When illuminated with magenta light, which contains red and blue wavelengths, the object absorbs the blue light and reflects only the red, appearing red.
How is the brightness of light determined?
The brightness of light is determined by the intensity of the light source and the distance from the source to the object being illuminated. The closer the object is to the light source and the more intense the light, the brighter the light will appear.
What happens when you put an object in front of the light?
When you put an object in front of light, the object can either absorb, reflect, or transmit the light. If the object absorbs the light, it appears dark. If it reflects the light, it appears illuminated. If the object transmits the light, it may appear transparent or colored.
What color does an object appear to be if it absorbs all the colors of light?
If an object absorbs all the colors of light, it will appear to be black. It is the reflected part of the spectrum that gives an object its color.
Why an object which appears yellow in daylight appears red when illuminated with magenta light?
The object absorbs all colors except yellow in daylight, reflecting yellow light. When illuminated with magenta light, the object absorbs magenta light and reflects red light due to the mixing of magenta and yellow light together. This causes the object to appear red under magenta light.
