The frequency of ultraviolet rays is?

Options

A. `10^(10)` Hz
B. `10^(15)`Hz
C. `10^(19)`Hz
D. `10^(12)`Hz

Explanation

To determine the frequency of ultraviolet rays, we can follow these steps:

### Step 1: Understand the Electromagnetic Spectrum
Ultraviolet (UV) rays are part of the electromagnetic spectrum, which includes various types of electromagnetic radiation categorized by their frequency and wavelength.

### Step 2: Identify the Frequency Range for Ultraviolet Rays
The frequency of ultraviolet rays typically ranges from approximately \(8 \times 10^{14}\) Hz to \(3 \times 10^{16}\) Hz. This information is crucial for identifying the correct answer from the given options.

### Step 3: Analyze the Given Options
The options provided are:
1. \(10^{10}\) Hz
2. \(10^{15}\) Hz
3. \(10^{19}\) Hz
4. \(10^{12}\) Hz

### Step 4: Compare the Options with the UV Frequency Range
Now, we compare each option with the frequency range of ultraviolet rays:
- \(10^{10}\) Hz is too low (not in the UV range).
- \(10^{12}\) Hz is also too low (not in the UV range).
- \(10^{15}\) Hz falls within the UV frequency range.
- \(10^{19}\) Hz is too high (not in the UV range).

### Step 5: Conclusion
Based on the analysis, the only option that lies within the frequency range of ultraviolet rays is \(10^{15}\) Hz. Therefore, the correct answer is:

**The frequency of ultraviolet rays is \(10^{15}\) Hz.**
