4. In the diagram below, you will see three materials. Each has its index of refraction given. (8 points) air=n1
glass=n1.5
water=n1.33

A. On the diagram above, trace the path of a light ray through these materials. (4 points)

i. From air into glass

ii. From glass into water

B. Justify your choice of path in words. (4 points)

i. From air into glass

ii. From glass into water

yup its correct its: c) b b

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
