UV radiation and IR radiation have the range

Options

A. `{:("UV Radiation","IR Radiation"),("more than 100nm","less than 400 nm"):}
B. `{:("UV Radiation","IR Radiation"),("less than 400 nm","more than 700nm"):}
C. `{:("UV Radiation","IR Radiation"),("equal to 400 nm","equal to 700 nm"):}
D. `{:("UV Radiation","IR Radiation"),("less than 100 nm","more than 100 nm"):}

Answer

To determine the ranges of UV (ultraviolet) radiation and IR (infrared) radiation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding UV Radiation**:
- UV radiation is part of the electromagnetic spectrum that has wavelengths shorter than visible light.
- The visible light spectrum ranges from approximately 400 nm (violet) to 700 nm (red).
- Therefore, UV radiation has wavelengths that are less than 400 nm.

2. **Understanding IR Radiation**:
- IR radiation is part of the electromagnetic spectrum that has wavelengths longer than visible light.
- Since the visible light spectrum ends at about 700 nm (red), IR radiation starts from this point and extends to longer wavelengths.
- Thus, IR radiation has wavelengths greater than 700 nm.

3. **Summarizing the Ranges**:
- **UV Radiation**: Wavelengths less than 400 nm.
- **IR Radiation**: Wavelengths greater than 700 nm.

4. **Conclusion**:
- The ranges for UV and IR radiation can be summarized as:
- UV radiation: Less than 400 nm
- IR radiation: More than 700 nm

### Final Answer:
- UV radiation has a range of less than 400 nm, and IR radiation has a range of more than 700 nm.
