Because we should convert units within the metric system
Refractive index is the ration of sin i to sin r where i is the incident angle and r is the refraction angle.
Therefore, refractive index = sin 79.5 / sin 39.6
= 1.542
The refractive index may be given by the ratio of refractive index of medium 2 to refractive index of medium 1.
Therefore, 1.542 = n/1.0003
n = 1.5425
≈ 1.54
Medium 2 is sodium chloride, refractive index of 1.54
Because There are frictional energy losses causing a slight downslope instead of a

The spring constant of the spring is 18.18 N/m.
<h3>State Hooke's law?</h3>
Hokes's law states that, as long as the elastic limit of a body is not exceeded, the extension of the body is directly proportional to its force applied . Mathematically, we can write the Hooke's law as;
F = Ke
F = force applied
K = force constant
e = extension
Now;
F = 6N
K = ??
e = 33cm or 0.33 m
Thus
K = F/e
K = 6N/0.33 m
K = 18.18 N/m
