1. What is Wavelength?

Wavelength is the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. It is typically measured in meters and is inversely proportional to frequency.

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

Where:

• \( \lambda \) — Wavelength (meters)
• \( v \) — Wave velocity (meters per second)
• \( f \) — Frequency (hertz)

Explanation: The wavelength is calculated by dividing the wave velocity by its frequency. Higher frequencies result in shorter wavelengths.

3. Importance of Wavelength Calculation

Details: Calculating wavelength is essential in physics, engineering, and telecommunications for designing antennas, understanding wave propagation, and analyzing wave behavior in different media.

4. Using the Calculator

Tips: Enter wave velocity in m/s and frequency in Hz. Both values must be positive numbers. For electromagnetic waves in vacuum, use speed of light (299,792,458 m/s).

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light?
A: The speed of light in vacuum is exactly 299,792,458 meters per second (about 3×10⁸ m/s).

Q2: How does wavelength relate to color?
A: In visible light, different wavelengths correspond to different colors (violet ~400nm to red ~700nm).

Q3: What's the wavelength range of radio waves?
A: Radio waves range from about 1 millimeter to 100 kilometers in wavelength.

Q4: How does medium affect wavelength?
A: While frequency remains constant, wavelength changes when waves enter different media due to changes in wave speed.

Q5: What's the relationship between energy and wavelength?
A: Energy is inversely proportional to wavelength (shorter wavelength = higher energy).
