Answer:
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.

Answer: The half-reactions represents reduction are as follows.
Explanation:
A half-reaction where addition of electrons take place or a reaction where decrease in oxidation state of an element takes place is called reduction-half reaction.
For example, the oxidation state of Cr in
is +6 which is getting converted into +3, that is, decrease in oxidation state is taking place as follows.
![Cr_{2}O^{2-}_{7} + 3 e^{-} \rightarrow Cr^{3+}](https://tex.z-dn.net/?f=Cr_%7B2%7DO%5E%7B2-%7D_%7B7%7D%20%2B%203%20e%5E%7B-%7D%20%5Crightarrow%20Cr%5E%7B3%2B%7D)
Similarly, oxidation state of Mn in
is +7 which is getting converted into +2, that is, decrease in oxidation state is taking place as follows.
![MnO^{2-}_{4} + 5 e^{-} \rightarrow Mn^{2+}](https://tex.z-dn.net/?f=MnO%5E%7B2-%7D_%7B4%7D%20%2B%205%20e%5E%7B-%7D%20%5Crightarrow%20Mn%5E%7B2%2B%7D)
Thus, we can conclude that half-reactions represents reduction are as follows.
Answer:
The methods commonly used to prepare emulsions can be divided into two categories
A) Dry gum method
B) Wet gum method
Answer:
Fault-block mountain
In geography, fault-block mountains arise when the Earth's crust pulls apart and divides. Some parts of the Earth are pushed upwards whereas the other moves downward forming a divergent boundary. In geological studies, a divergent boundary can be described as a linear feature which arises due to plate tectonics which are being pulled apart from each other. Hence, fault-block mountains are most likely to be seen in a divergent boundary.
Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill.
Answer:
Neutrons
Explanation:
Protons have a positive (+) charge.
Electrons have a negative (-) charge.
Neutrons have a neutral (0) charge.
