1. What is MHz to nm Conversion?

The MHz to nm conversion calculates the wavelength of electromagnetic radiation from its frequency. This is particularly useful in fields like radio astronomy, spectroscopy, and telecommunications.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \lambda \) — Wavelength in nanometers (nm)
• \( f \) — Frequency in megahertz (MHz)
• \( 3 \times 10^{11} \) — Conversion factor (speed of light in nm/s divided by 1,000,000 for MHz)

Explanation: The equation converts frequency to wavelength using the fundamental relationship between these two properties of electromagnetic waves.

3. Importance of Wavelength Calculation

Details: Knowing the wavelength is essential for designing antennas, optical systems, and understanding how electromagnetic waves interact with matter.

4. Using the Calculator

Tips: Enter frequency in MHz (must be positive value). The calculator will output the corresponding wavelength in nanometers.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light used in this calculation?
A: The calculation uses 3 × 10^17 nm/s (speed of light in nanometers per second).

Q2: Can I use this for any electromagnetic wave?
A: Yes, this conversion works for all electromagnetic waves in vacuum. For other media, the speed of light would be different.

Q3: What's the practical application of this conversion?
A: Useful for antenna design, spectroscopy, laser technology, and understanding electromagnetic wave properties.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your frequency measurement.

Q5: Can I convert nm back to MHz?
A: Yes, by rearranging the equation: \( f (MHz) = \frac{3 \times 10^{11}}{\lambda (nm)} \)
