What is the frequency range of light seen
when you look at a black object?
1. All possible colors
2. ultra violet colors
3. no visible colors
4. infra-red colors
5. all visible colors
6. No possible colors
3. no visible colors
When you look at a black object, no visible colors are seen because black objects absorb all light that strikes them and do not reflect any of it back to your eyes. Therefore, the frequency range of light seen when you look at a black object is not within the visible spectrum.
The correct answer is 3. no visible colors.
When you look at a black object, it appears black because it absorbs most of the light that falls on it, reflecting very little back to your eyes. Light is made up of a range of different frequencies, which we perceive as different colors. However, since the black object absorbs most or all of the light, none or very little reaches your eyes, resulting in no visible colors.
