1. What is Wien's Displacement Law?

Wien's Displacement Law describes the relationship between the temperature of a blackbody and the wavelength at which it emits the most radiation. It states that the peak wavelength is inversely proportional to the temperature.

2. How Does the Calculator Work?

The calculator uses Wien's Displacement Law:

Where:

• \( \lambda_{\text{max}} \) — Peak wavelength (m)
• \( b \) — Wien's displacement constant (2.897 × 10⁻³ m·K)
• \( T \) — Temperature (K)

Explanation: As the temperature of a blackbody increases, the peak wavelength of emitted radiation shifts to shorter wavelengths.

3. Importance of Peak Wavelength Calculation

Details: Calculating the peak wavelength is crucial for understanding thermal radiation properties, astrophysics applications, and designing thermal imaging systems.

4. Using the Calculator

Tips: Enter temperature in Kelvin. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a blackbody?
A: A blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.

Q2: Why is the temperature in Kelvin?
A: Kelvin is the SI base unit for thermodynamic temperature and ensures proper calculation results without negative values.

Q3: What are typical applications of this law?
A: Applications include determining star temperatures, thermal camera design, and understanding thermal radiation in various engineering fields.

Q4: Are there limitations to this law?
A: The law applies specifically to blackbody radiation and may not accurately describe real materials that don't behave as perfect blackbodies.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact for ideal blackbodies, but real-world applications may require additional considerations for material properties.
