Practically ozone layer absorbs the radiation of wavelength

Options

A. less than `3xx10^(-7)m`
B. greater than `3xx10^(-7)m`
C. equal to `3xx10^(-7)m`
D. all the above

Answer

To solve the question regarding the wavelength of radiation absorbed by the ozone layer, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Atmosphere**:
- The Earth's atmosphere consists of several layers, including the troposphere and stratosphere. The ozone layer is located in the stratosphere.

2. **Identify the Function of the Ozone Layer**:
- The primary function of the ozone layer is to absorb harmful ultraviolet (UV) radiation from the sun.

3. **Determine the Wavelength Range**:
- It is known that the ozone layer effectively absorbs UV radiation in the wavelength range of approximately 200 nanometers (nm) to 310 nanometers (nm).

4. **Convert Wavelengths to Meters**:
- To express the wavelengths in meters:
- 200 nm = 200 x 10^-9 m = 2 x 10^-7 m
- 310 nm = 310 x 10^-9 m = 3.1 x 10^-7 m

5. **Select the Correct Option**:
- Based on the information gathered, the correct answer to the question about the wavelength range absorbed by the ozone layer is between 200 nm and 310 nm (or 2 x 10^-7 m to 3.1 x 10^-7 m).

### Final Answer:
The ozone layer absorbs radiation in the wavelength range of approximately 200 nm to 310 nm.
