Light passes from a material with index of refraction 1.25 to one with index of refraction 1.72. the angle of incidence is 34.3°. what is the angle of refraction?

angle of refraction is 24.17°

Explanation:

given data

index of refraction n1 =  1.25

index of refraction n2 = 1.72

angle of incidence θ1 =  34.3°

to find out

angle of refraction (θ2)

solution

we will apply here snells law that is

n1 sinθ1 = n2 sinθ2    1

here put all these value and find θ2

1.25 sin34.3 = 1.72 sinθ2  

sinθ2  = 0.70440 /1.72

sinθ2 = 0.4095

θ2 = 24.17°

so here angle of refraction is 24.17°

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
