Answer:
Silver
Explanation:
Silver is an important element in the manufacturing process of mirrors. Silver is used to make mirrors through the process we call "silvering". Silvering is a process in which a glass is coated with reflective substances so as to produce reflections, and then mirrors.
In Silvering process, Chlorine is also used. Stannous Chloride is the particular compound used to carry out the silvering, it has the chemical formula, SnCl₂
The medium is glass (index of refraction: 1.70)
Explanation:
We can solve the problem by using the concept of index of refraction.
The index of refraction of a medium is given by:
where
is the speed of light in a vacuum
v is the speed of light in the medium
For the medium in this problem, we have
So, the index of refraction of this medium is
And looking at tables of index of refraction of various materials, we see that various types of glass have index of refraction of 1.70.
