Question

I don't know b.

please explain how to find the wavelengths of each objects

3. 5 Example 3.0 2.5 2.0 Intensity 1.5 1.0 0.5 0.0 0 2.5x10 5.0x100 1.0x10* 1.5 x 10 2.0x10* Wavelength (Angstroms) a) What is the ratio of intensity between these two objects? b) What are the temperatures of the two objects? c) What are the Energy of the photons emitted at the two peaks? d) How does the compare to the power output (assuming same surface areas) of the two objects?
