Have you ever wondered why hot objects glow with different colours, or why the sun appears yellow? Let's explore the fascinating world of black body radiation through interactive simulations that connect quantum physics with everyday observations.
A black body is an idealized object that absorbs all incoming electromagnetic radiation. While perfect black bodies don't exist in nature, stars and hot objects closely approximate this behaviour. Our interactive simulation lets you visualize how objects emit radiation at different temperatures.
The colour of a heated object tells us about its temperature. Through our interactive simulation, you'll explore:
- How emission spectra change with temperature
- The shift from red to blue as temperature increases
- The relationship between wavelength and energy
The simulation demonstrates how the peak wavelength of emission changes with temperature:
- Observe the inverse relationship between temperature and peak wavelength
- Understand why the sun appears yellow
- Explore how stars of different temperatures have different colours
Our interactive simulation brings energy calculations to life:
- See how total radiated power varies with temperature
- Visualize the T⁴ relationship
- Calculate energy emission rates for different objects
The interactive simulation offers comprehensive tools for learning:
- Real-time spectral distribution graphs
- Adjustable temperature controls
- Energy distribution visualization
- Comparison tools for different temperatures
Experience the birth of quantum physics through:
- Visualization of the ultraviolet catastrophe
- Planck's quantum hypothesis in action
- Energy quantization effects on spectra
Discover how black body radiation impacts:
- Astronomy: Determining star temperatures
- Industry: Temperature measurement in furnaces
- Medical imaging: Infrared body scanning
- Environmental science: Climate studies and greenhouse effect
