If everything above 50% of light energy reflected is visible to the human eye, is red light part of the mixture of colors seen in light reflected by chlorophyll? Explain your answer.
What is the answer
no. Think why grass, and plants are green when growing.
Yes, red light is indeed part of the mixture of colors seen in light reflected by chlorophyll. Chlorophyll is a pigment found in plants that absorbs light energy for the process of photosynthesis. However, it only absorbs certain wavelengths of light, while reflecting others.
Chlorophyll primarily absorbs blue and red light, but it reflects green light, giving plants their characteristic green color. This means that when white light, which contains all the colors in the visible spectrum, shines onto chlorophyll, it will absorb some wavelengths (like blue) and reflect others (like green).
Since red light is not absorbed by chlorophyll but instead reflected, it is part of the mixture of colors seen in the light reflected by chlorophyll. Humans can perceive this reflected red light, along with the green light, and interpret it as the color green, which is what we typically see in leaves.
To determine if red light is part of the mixture of colors seen in light reflected by chlorophyll, we need to understand how chlorophyll interacts with light. Chlorophyll is a pigment found in plants that plays a key role in photosynthesis.
Visible light is made up of different colors, ranging from violet to red, which can be separated using a prism or viewed as a rainbow. When white light hits an object, it can be absorbed, transmitted, or reflected. The color we perceive is the result of the reflected light.
Chlorophyll primarily absorbs light in the red and blue regions of the electromagnetic spectrum. It has a high absorption rate for red light and a slightly lower absorption rate for blue light. This means that when chlorophyll is exposed to white light, it absorbs most of the red and blue light, but reflects green light. This reflected green light is what we perceive, giving plants their green color.
So, if we consider the statement that everything above 50% of light energy reflected is visible to the human eye, we can infer that some red light is indeed reflected by chlorophyll. While most red light is absorbed, there will be a certain percentage of red light that is not absorbed and, therefore, reflected by chlorophyll.
In conclusion, while chlorophyll primarily reflects green light, it does reflect a portion of the red light as well, making it part of the mixture of colors seen in light reflected by chlorophyll.
