Question

When determining the wavelength of peak intensity for thermal radiation, the temperature of the object is a crucial factor. If the object's temperature increases:"

a) The wavelength of peak intensity decreases.
b) The wavelength of peak intensity increases.
c) The wavelength of peak intensity remains constant.
d) The wavelength of peak intensity is not affected by temperature.

Answer 1

The wavelength of peak intensity for thermal radiation decreases as the temperature of the object increases.

Step-by-step explanation:

The wavelength of peak intensity for thermal radiation decreases as the temperature of the object increases. The graph shows that as the temperature increases, the wavelength at which the maximum power is emitted becomes shorter. This is because hotter objects give off a larger fraction of their energy at shorter wavelengths (higher energies).
