The metal conducts the heat, which makes cooking easier.
The velocity of an object determines if it is moving. If the velocity is zero, it is not moving. If it has a positive velocity, then it is moving forward. If it has a negative velocity, then it is moving backwards.
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.
