Oraza de lumina cade sub un unghi de incidenta de 30 de grade pe o suprafata plana ce separa doua materiale transparente cu indicii de refractie 1,60 si 1,40.
calculati unghiul de refractie (din mediul cu indicele de refractie mai mic)

Explanation:

The question in english is:

A ray of light falls under an angle of incidence of 30 degrees on a flat surface that separates two transparent materials with index of refractions 1.60 and 1.40, respectively.

Calculate the angle of refraction (from the environment with the lower index of refraction)

According to Snell’s Law:  

(1)  

Where:  

is the first medium index  of refraction

is the second medium index  of refraction

is the angle of the incident ray  

is the angle of the refracted ray

We need to find from (1):

(2)  

(3)

Finally:

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
