1. What Is Wavelength And Frequency?

Wavelength (λ) is the distance between two consecutive peaks of a wave, while frequency (f) is how many waves pass a point in one second. They are inversely related - higher frequency means shorter wavelength.

2. How Does The Calculator Work?

The calculator uses the wavelength formula:

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

Where:

Explanation: This formula shows that as frequency increases, wavelength decreases, and vice versa.

3. Why Is This Important?

Details: Understanding wavelength and frequency helps us understand different types of electromagnetic waves, from radio waves to visible light to X-rays.

4. Using The Calculator

Tips: Enter frequency in Hertz (Hz). The calculator will show you the corresponding wavelength in meters.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light?
A: The speed of light is approximately 300,000,000 meters per second (3×10⁸ m/s).

Q2: What are some examples of different wavelengths?
A: Radio waves have long wavelengths (meters to kilometers), visible light has very short wavelengths (400-700 nanometers), and gamma rays have the shortest wavelengths.

Q3: Why does light have different colors?
A: Different colors of light have different wavelengths. Red light has the longest wavelength and violet light has the shortest wavelength in the visible spectrum.

Q4: Can sound waves use this formula too?
A: Sound waves use a similar formula, but with the speed of sound (343 m/s in air) instead of the speed of light.

Q5: What is Hertz (Hz)?
A: Hertz is the unit of frequency that measures how many waves pass a point each second. 1 Hz = 1 wave per second.
