In electromagnetic radiation, which of the following,…… rays has greater wavelength than visible light ?

Options

A. U.V.
B. I.R
C. Gamma
D. X-rays

Answer

To solve the question regarding which rays have a greater wavelength than visible light, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Electromagnetic Spectrum**:
The electromagnetic spectrum is a range of all types of electromagnetic radiation, which are classified based on their wavelengths. The order of electromagnetic waves from shortest to longest wavelength is as follows:
- Gamma rays
- X-rays
- Ultraviolet (UV) rays
- Visible light
- Infrared (IR) rays
- Microwaves
- Radio waves

2. **Identify the Wavelength of Visible Light**:
Visible light has a specific range of wavelengths, typically from about 400 nm (violet) to 700 nm (red).

3. **Determine Which Rays Have Greater Wavelengths**:
From the spectrum, we can see that:
- UV rays have shorter wavelengths than visible light.
- IR rays have longer wavelengths than visible light.
- Microwaves and radio waves also have longer wavelengths than visible light.

4. **Analyze the Given Options**:
The options provided are:
- UV rays
- IR rays
- Gamma rays
- X rays

Based on our understanding:
- **UV rays**: Incorrect (shorter than visible light)
- **IR rays**: Correct (greater than visible light)
- **Gamma rays**: Incorrect (shorter than visible light)
- **X rays**: Incorrect (shorter than visible light)

5. **Conclusion**:
The only ray from the options that has a greater wavelength than visible light is **IR rays**.

### Final Answer:
**IR rays** have greater wavelength than visible light.
