Answer:

Explanation:
Index of refraction:
where
is the refractive index,
is the speed of light in vacuum and
is the speed of light in medium.
The speed of light in vacuum is 
Speed of light in medium is 
Thus,

Index of refraction of this substance through yellow light is 
Answer:
The person has no displacement
Explanation:
The given parameters are
The location of the person = The equator
The distance covered in one revolution = Total distance around the body
The total distance around the Earth = The circumference of the Earth = 40.075 kilometres
The total distance moved by the person standing at the equator during the Earths complete revolution = 40,075 kilometres
The initial location of the person in relation to a fixed point in space outside Earth at the start of the revolution = x km
The final location of the person in relation to the fixed point in space outside Earth at the completion of the revolution = x km
The displacement = Change in position = Final location - Initial location
∴ The displacement = x km - x km = 0 km.
