Final answer:
The statement that visible light is in the middle yellow in 'scenario c' is false, as yellow light on white paper doesn't denote the middle of the visible spectrum, which is generally considered to be green, and not yellow.
Step-by-step explanation:
The question is asking if visible light being in the middle yellow in a given scenario is true. The statement is false since 'scenario c' refers to a situation where yellow light shines on white paper. This means that the paper appears yellow because it reflects the yellow light shined upon it. In terms of color and color vision, when a scenario mentions the middle spectrum of visible light, it generally refers to green. Green is indeed in the middle of the visible spectrum, not yellow. Yellow light is produced by a mixture of red and green light in additive color mixing, and it's situated towards the longer wavelength end of the spectrum, near the green midpoint.
In the context provided, when discussing scenarios of light detection and observation, such as the outcome when yellow light shines on a white paper or white light on yellow paper, yellow is not necessarily in the middle of the visible spectrum. Instead, it's often used to illustrate how we perceive colors based on the light that objects reflect or absorb. To clarify, visible light encompasses all the colors that the human eye can detect, ranging from red to violet, with green being approximately in the middle of these colors.
