1. What Is Wavelength Of Light?

Wavelength is the distance between two consecutive peaks or troughs in a wave. For light waves, it determines the color we see! Different colors have different wavelengths.

2. How Does The Calculator Work?

The calculator uses the wavelength formula:

Where:

• \( \lambda \) — Wavelength in meters (m)
• \( c \) — Speed of light (3 × 10⁸ m/s)
• \( f \) — Frequency in Hertz (Hz)

Explanation: The higher the frequency, the shorter the wavelength. The lower the frequency, the longer the wavelength!

3. Importance Of Wavelength Calculation

Details: Understanding wavelength helps us learn about light colors, how radios work, and why the sky is blue! It's a fundamental concept in physics.

4. Using The Calculator

Tips: Enter the frequency of the light wave in Hertz (Hz). The frequency must be a positive number. The calculator will show you the wavelength in meters.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light?
A: The speed of light is 299,792,458 meters per second, but we often use 3 × 10⁸ m/s for calculations!

Q2: What are some typical light wavelengths?
A: Red light has wavelengths around 700 nanometers, while violet light has wavelengths around 400 nanometers.

Q3: How is frequency related to energy?
A: Higher frequency light has more energy! That's why ultraviolet light can sunburn but visible light doesn't.

Q4: Can we see all wavelengths of light?
A: No! Humans can only see wavelengths between about 380-750 nanometers. This is called the visible spectrum.

Q5: Why is wavelength important for rainbows?
A: Rainbows show all the colors of visible light separated by their different wavelengths!
