Black body radiation

The title of the Project: Black body radiation

Purpose of the work:

  • Study the black body radiation.

Practical part

This is a little instruction to the virtual experiment.

Virtual experiment.

Step 1. Choose the settings depicted in the photo below.

Step 2. Increase the temperature. Notice that as you increase the temperature the peak of the graph becomes out of the scope, so adjust the scale accordingly. How does the wavelength change? Spectral power density? Press the camera button to save the graph. 

Step 3. Decrease the temperature. Adjust the scale if needed. How does the wavelength change? Spectral power density? Press the camera button to save the graph. 

Step 4. Make a conclusion. 

Conclusion

The power of black body radiation increases with the temperature. Whereas the wavelength of the radiation decreases with the temperature.
