1. What is the Wavelength Formula?

The wavelength formula calculates the distance between consecutive crests of a wave. For light waves, it's calculated using the speed of light and the frequency of the wave.

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 - as frequency increases, wavelength decreases, and vice versa.

3. Importance of Wavelength Calculation

Details: Calculating wavelength is essential in optics, telecommunications, and spectroscopy. It helps determine the color of visible light and the properties of electromagnetic radiation across the spectrum.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz). The value must be greater than 0. The calculator will automatically use the speed of light constant (3×10^8 m/s).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the wave speed is constant.

Q2: What are typical wavelength values for visible light?
A: Visible light wavelengths range from approximately 380 nm (violet) to 750 nm (red), corresponding to frequencies of about 400-790 THz.

Q3: Does the speed of light change in different media?
A: Yes, the speed of light is slower in materials other than vacuum, which affects wavelength calculations in those media.

Q4: Can this calculator be used for other types of waves?
A: While the formula is similar for all waves, this calculator specifically uses the speed of light constant, making it suitable only for electromagnetic waves.

Q5: How precise is the speed of light constant used?
A: The calculator uses 3×10^8 m/s, which is an approximation. The exact speed of light in vacuum is 299,792,458 m/s.
