1. What Are Wavelength, Frequency, and Energy?

Wavelength (λ) is the distance between successive crests of a wave, frequency (f) is the number of waves that pass a point per second, and energy (E) is the energy carried by a photon. These are fundamental properties of electromagnetic radiation.

2. How Does the Calculator Work?

The calculator uses the fundamental equations:

Where:

• \( \lambda \) — Wavelength (meters)
• \( f \) — Frequency (Hertz)
• \( E \) — Energy (Joules)
• \( c \) — Speed of light = 3 × 10⁸ m/s
• \( h \) — Planck's constant = 6.626 × 10⁻³⁴ J·s

Explanation: These equations show the relationship between the wave properties of light and the particle (photon) properties.

3. Importance of These Calculations

Details: These calculations are essential in physics, chemistry, and engineering for understanding electromagnetic radiation, quantum mechanics, spectroscopy, and various technological applications.

4. Using the Calculator

Tips: Enter any two known values (wavelength, frequency, or energy) and the calculator will compute the third missing value. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between wavelength and frequency?
A: Wavelength and frequency are inversely proportional through the speed of light: λ = c/f.

Q2: How is energy related to wavelength?
A: Energy is inversely proportional to wavelength: E = hc/λ. Shorter wavelengths carry more energy.

Q3: What are typical units for these measurements?
A: Wavelength in meters, frequency in Hertz (Hz), and energy in Joules (J). Often scientific notation is used.

Q4: Can this calculator handle different unit systems?
A: This calculator uses SI units. For other units, convert to meters, Hertz, and Joules first.

Q5: What are some practical applications?
A: These calculations are used in telecommunications, medical imaging, spectroscopy, solar energy, and quantum computing.
