Bright colours exhibited by spider.s web, exposed to sunlight are due to

Options

A. interference
B. resolution
C. diffraction
D. polarisation

Answer

**Step-by-Step Solution:**

1. **Understanding the Phenomenon**: The question asks about the bright colors exhibited by a spider's web when exposed to sunlight. To answer this, we first need to understand how light interacts with the spider's web.

2. **Nature of the Spider's Web**: A spider's web consists of very thin strands. These strands can be compared to the wavelength of visible light. When light from the sun hits the web, it interacts with these thin strands.

3. **Light Interaction**: The thin strands of the spider's web act as obstacles to the light waves. When light encounters these obstacles, it bends around them. This bending of light waves is known as diffraction.

4. **Result of Diffraction**: As the light waves bend around the strands of the web, they interfere with each other. This interference can cause certain colors to be enhanced while others may be diminished, resulting in the bright colors that we observe.

5. **Conclusion**: Therefore, the bright colors exhibited by the spider's web when exposed to sunlight are due to the phenomenon of diffraction.

**Final Answer**: The bright colors exhibited by a spider's web, exposed to sunlight, are due to **diffraction**.
