Answer: Because of the different wave speed from light and sound. Explanation: There is a major difference between the speed wave of light and sound, light travels at 186, 282 miles per second, and sound can travel at different speeds and its significantly slower so it is easier to measure it

4 atoms 
Explanation:
On the product side, we expect to find 4 atoms of the product. 
     An atom is the smallest indivisible particle that takes part in a chemical reaction. 
     An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom. 
     In this reaction we have: 
        2 elements:             Mg                O
on the reactant side: 
    We have two moles of Mg:   2 atoms of Mg
             1 mole of oxygen gas:   2 atoms of O
                              total atoms:    4 atoms
 According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed". 
 We expect to find 4 atoms of products which is MgO on the product side. 
               2Mg + O₂ →  2MgO + heat

Answer:
When you have a cloudy night, the clouds prevent heat from escaping through the atmosphere and into space. 
The clouds act like a blanket and trap the heat it, and that is why every time you have a cloudy night, it is always warmer than a clear night.
