The amount of light reflected depends upon

Options

A. the nature of material of the object only
B. the nature of the surface only
C. the smoothness of the surface only
D. all the above

Answer

### Step-by-Step Text Solution:

1. **Understanding Reflection**: The amount of light reflected when it strikes a surface is determined by several factors. Reflection occurs when light bounces off a surface, and the characteristics of that surface play a crucial role in how much light is reflected.

2. **Nature of the Material**: The first factor is the nature of the material of the surface. Materials can be classified as opaque, transparent, or translucent:
- **Opaque**: These materials do not allow light to pass through. They can reflect all or some of the light, depending on their properties.
- **Transparent**: These materials allow light to pass through them. Most of the light will transmit through, and very little will be reflected.
- **Translucent**: These materials allow some light to pass through but scatter it. They reflect some light and transmit some light.

3. **Surface Texture**: The second factor is the texture of the surface. The texture can be smooth or rough:
- **Smooth Surfaces**: These surfaces tend to reflect light uniformly, leading to clearer reflections (like a mirror).
- **Rough Surfaces**: These surfaces scatter the light in different directions, leading to diffuse reflection, which means less light is reflected in a single direction.

4. **Smoothness of the Surface**: The smoothness of the surface is also crucial. A smoother surface will generally reflect more light in a coherent manner, while a rough surface will scatter the light, reducing the amount of light that is reflected in a specific direction.

5. **Conclusion**: Therefore, the amount of light reflected depends on:
- The nature of the material (opaque, transparent, translucent)
- The texture of the surface (smooth or rough)
- The smoothness of the surface
