The angle of incidence at a solid/liquid boundary is 59.6a? °, and the index of refraction of the solid is n = 1.55. (a what must be the index of refraction of the liquid such that the direction of the light entering the liquid is not changed? (b what is the largest index of refraction that the liquid can have, such that none of the light is transmitted into the liquid and all of it is reflected back into the solid?

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
