Options

A. `a lt d , b gt c`
B. ` a lt b , b lt c`
C. ` a gt b gt c `
D. ` a gt b, b gt c`

Answer

To solve the problem regarding the frequencies of X-rays, Gamma rays, and visible light, we need to understand the order of electromagnetic waves based on their frequencies.

### Step-by-Step Solution:

1. **Identify the Frequencies**:
- Let the frequency of X-rays be \( A \).
- Let the frequency of Gamma rays be \( B \).
- Let the frequency of visible light be \( C \).

2. **Understand the Order of Electromagnetic Waves**:
- The electromagnetic spectrum is arranged in order of increasing wavelength and decreasing frequency as follows:
- Cosmic Rays > Gamma Rays > X-rays > Ultraviolet (UV) > Visible Light > Infrared > Microwaves > Radio Waves.

3. **Compare the Frequencies**:
- From the order of the electromagnetic spectrum:
- Gamma rays (B) have a higher frequency than X-rays (A).
- X-rays (A) have a higher frequency than visible light (C).
- Therefore, we can conclude:
- \( B > A \) (Gamma rays have a higher frequency than X-rays)
- \( A > C \) (X-rays have a higher frequency than visible light)
- \( B > C \) (Gamma rays have a higher frequency than visible light)

4. **Summarize the Relationships**:
- From the comparisons, we can summarize:
- \( B > A > C \)

5. **Choose the Correct Option**:
- Based on the relationships derived, the correct statement among the options provided would be:
- \( A < B \) and \( B > C \) (which means X-rays have a lower frequency than Gamma rays, and Gamma rays have a higher frequency than visible light).
