I think the correct answer would be negative change in enthalpy, low temperature and negative entropy. Freezing of water is an exothermic process which means heat is released to the surroundings so negative enthalpy. And this is seen in the change to a lower temperature. Entropy is negative which signifies that there is more order as water freezes.
Use the formula E=hv, h=plancks constant and v=frequency
use the formula c=v*lambda to find v
the answer will be 2.88*10^-23J

All of the above
Explanation:
Scientists can use spectra analysis of stars to determine:
- Surface temperature of the star
- Core temperature of stars
- Elements in the core of the star
- Elements on the surface of the star
Spectra analysis is the analysis or interpretation of the electromagnetic emissions from a matter.
They are very useful in indirect and descriptive studies of astronomical bodies since it might be very difficult of come in close contact with them.
Emissions spectrum typifies every matter in nature since all bodies emits specific radiations.
Using spectra analysis, scientists can determine the temperature that typifies an emission and the elements that might might be producing such signatures.
