1. What is the Wavelength Formula?

The wavelength formula calculates the distance between consecutive crests of a wave using the speed of light and frequency. It's fundamental in physics and electromagnetic radiation studies.

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

\[ \lambda = \frac{c}{f} \]

Where:

Explanation: The formula shows the inverse relationship between wavelength and frequency - higher frequencies result in shorter wavelengths.

3. Importance of Wavelength Calculation

Details: Wavelength calculation is essential in telecommunications, spectroscopy, astronomy, and understanding electromagnetic radiation properties across different frequency bands.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz). The value must be positive and non-zero. The calculator uses the constant speed of light value of 3×10⁸ m/s.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light constant?
A: The speed of light in vacuum is exactly 299,792,458 m/s, but 3×10⁸ m/s is commonly used for calculations and approximations.

Q2: How does wavelength relate to energy?
A: Shorter wavelengths correspond to higher energy radiation according to the formula E = hc/λ, where h is Planck's constant.

Q3: What are typical wavelength ranges?
A: Radio waves: >1m, Microwaves: 1mm-1m, Infrared: 700nm-1mm, Visible light: 400-700nm, UV: 10-400nm, X-rays: 0.01-10nm, Gamma rays: <0.01nm.

Q4: Can this formula be used for sound waves?
A: Yes, but replace c with the speed of sound (approximately 343 m/s in air at 20°C) instead of the speed of light.

Q5: Why is wavelength important in antenna design?
A: Antenna size and design are typically proportional to the wavelength of the radiation they're intended to transmit or receive.
