Plane polarized light can be obtained by using

Options

A. A Nicole prism
B. Tourmaline crystal
C. Convex lens
D. Both (1) & (2)

Answer

To solve the question of how plane polarized light can be obtained, we need to understand the concept of polarization and the methods used to achieve it.

### Step-by-Step Solution:

1. **Understanding Plane Polarized Light**:
- Plane polarized light is light in which the electric field oscillates in a single plane. This is different from unpolarized light, where the electric field oscillates in multiple planes.

2. **Methods of Obtaining Plane Polarized Light**:
- There are several methods to obtain plane polarized light. The most common methods include:
- **Using a Polarizer**: A polarizer is an optical device that allows light waves of a specific polarization to pass through while blocking others. Common polarizers include Polaroid filters.
- **Reflection**: When unpolarized light reflects off a non-metallic surface at a specific angle (known as Brewster's angle), the reflected light becomes partially polarized.
- **Scattering**: Light can also become polarized when it is scattered, such as when sunlight scatters in the atmosphere.

3. **Identifying Options**:
- If the question provides options, we need to identify which of the given options are capable of producing plane polarized light. For example, if the options include a polarizer and a mirror, the polarizer would be the correct choice.

4. **Conclusion**:
- Based on the methods discussed, plane polarized light can be obtained using a polarizer or through reflection at Brewster's angle. If the question provides specific options, we would select the relevant ones based on this understanding.
