Answer:
1.) Total distance = 70 m
2.) Total displacement = +30m
Explanation:
Distance is a scaler quantity. That is, we will be concerned about its magnitude only and not direction.
Total distance = 10 + 20 + 40 = 70 m
While displacement is a vector quantity. We will consider both the magnitude and its direction.
Forward direction will be positive while backward direction will be negative
Total displacement = +10 - 20 + 40
Total displacement = +30 m
Answer: The refractive index or n shows the relationship between c and the speed v when light travels through a material. The equation is n=c/v. In water, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water, than it travels through glass.
