Which component of electromagnetic spectrum have maximum wavelength?

Options

A. radio waves
B. Visible spectrum
C. Gamma rays
D. X-rays

Explanation

To determine which component of the electromagnetic spectrum has the maximum wavelength, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Electromagnetic Spectrum**: The electromagnetic spectrum is a range of all the different frequencies of electromagnetic radiation. It includes various types of waves, listed from the longest wavelength to the shortest wavelength.

2. **Identify the Components of the Spectrum**: The components of the electromagnetic spectrum, in order of decreasing wavelength (or increasing frequency), are:
- Radio Waves
- Microwaves
- Infrared Radiation
- Visible Light
- Ultraviolet (UV) Radiation
- X-rays
- Gamma Rays

3. **Analyze Wavelength Trends**: As we move from left to right in the electromagnetic spectrum, the wavelength decreases while the frequency and energy increase. Conversely, moving from right to left, the wavelength increases.

4. **Locate the Options Given**: The options provided in the question are:
- Radio Waves
- Visible Spectrum
- Gamma Rays
- X-rays

5. **Determine Which Has the Maximum Wavelength**: Among the options listed, radio waves are located at the leftmost side of the electromagnetic spectrum, indicating they have the longest wavelength compared to the other components.

6. **Conclude the Answer**: Therefore, the component of the electromagnetic spectrum that has the maximum wavelength is **Radio Waves**.

### Final Answer:
**Radio Waves** have the maximum wavelength among the given options.
