For a green coloured body :–

Options

A. Reflection coefficient for green colour is greatest.
B. Transmission coefficient for green colour is greatest
C. Absorption coefficient for red colour is minimum
D. None

Answer

To solve the question regarding a green-colored body, we need to analyze how it interacts with light, specifically focusing on reflection, absorption, and transmission. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Interaction of Light with the Body
When light (radiation) falls on a body, it can either be reflected, absorbed, or transmitted. For a green-colored body, we need to determine how it interacts with different wavelengths of light.

**Hint:** Consider the properties of light and how colors are perceived based on reflection and absorption.

### Step 2: Identify the Color of the Body
A green-colored body appears green because it reflects green light and absorbs other colors. This means that the body does not reflect red, blue, or yellow light but primarily reflects green light.

**Hint:** Recall that the color we see is due to the wavelengths of light that are reflected by the object.

### Step 3: Coefficients of Reflection, Absorption, and Transmission
- **Reflection Coefficient (R):** This is the ratio of the reflected light to the incident light. For a green body, the reflection coefficient for green light will be high since it reflects green light effectively.
- **Absorption Coefficient (A):** This is the ratio of absorbed light to the incident light. Since the body absorbs other colors and reflects green, the absorption coefficient for those colors will be higher.
- **Transmission Coefficient (T):** This is the ratio of transmitted light to the incident light. A green body typically does not transmit light well in the green spectrum; it reflects it instead.

**Hint:** Remember that the sum of the reflection, absorption, and transmission coefficients equals 1.

### Step 4: Analyze the Given Options
1. **Reflection coefficient for green color is greatest.** - This is true because the body reflects green light effectively.
2. **Transmission coefficient of green color is greatest.** - This is false; the body does not transmit green light.
3. **Absorption coefficient for red color is minimum.** - This is false; the body absorbs red light since it reflects green.

**Hint:** Evaluate each statement based on the understanding of how a green body interacts with light.

### Step 5: Conclusion
Based on the analysis, the correct answer is that the reflection coefficient for green color is greatest. Therefore, the first option is correct.

**Final Answer:** The reflection coefficient for green color is greatest.
