Options

A. `X- ` rays `gt` UV rays `gt` Microwaves `gt` Radio waves
B. Radio waves `gt` Microwaves `gt` UV rays `gt` x- rays
C. UV - rays `gt` X - rays `gt` radio waves `gt` Microwaves
D. Radio waves `gt` Microwaves `gt` x - rays `gt` UV rays

Answer

To solve the question regarding the correct sequence of frequency of electromagnetic radiations in the electromagnetic spectrum, 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 radiation such as radio waves, microwaves, infrared, visible light, ultraviolet (UV) rays, X-rays, and gamma rays.

2. **List the Types of Radiation in Order of Increasing Frequency**: The correct order of the electromagnetic spectrum from lowest frequency to highest frequency is:
- Radio Waves
- Microwaves
- Infrared Rays
- Visible Light
- Ultraviolet (UV) Rays
- X-rays
- Gamma Rays

3. **Identify the Relationship Between Frequency and Wavelength**: It is important to note that frequency and wavelength are inversely related. As frequency increases, wavelength decreases. Therefore, the order of frequency from lowest to highest is the same as moving from radio waves to gamma rays.

4. **Analyze the Given Options**:
- **Option A**: X-rays > UV rays > Microwaves > Radio waves (Incorrect)
- **Option B**: Radio waves > Microwaves > UV rays > X-rays (Incorrect)
- **Option C**: UV rays > X-rays > Radio waves > Microwaves (Incorrect)
- **Option D**: Radio waves > Microwaves > X-rays > UV rays (Incorrect)

5. **Determine the Correct Option**: Based on the correct order of the electromagnetic spectrum, none of the options provided correctly reflect the increasing order of frequency. However, the correct sequence should start from radio waves and end with gamma rays. The closest correct sequence based on the provided options is Option A, which correctly places X-rays before UV rays.

### Conclusion:
The correct sequence of frequency of the electromagnetic radiations in the electromagnetic spectrum is:
- Radio Waves < Microwaves < Infrared < Visible Light < UV Rays < X-rays < Gamma Rays.

Thus, the answer is **Option A** (though it is not entirely correct as presented).
