Well first, how do we determine force?
Answer:
Buoyant Force: Cause and Calculation
The result is a net upward force (a buoyant force) on any object in any fluid. If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink.

Answer:
The index of refraction of quartz for violet light is 1.47.
Explanation:
It is given that, a narrow beam of white light is incident on a sheet of quartz.
The beam disperses in the quartz, with red light at an angle,
wrt to the normal and violet light traveling at an angle of 
The index of refraction of quartz for red light is 1.45.
We need to find the index of refraction of quartz for violet light.
Using Snell's law of red light as follows :

Here,
is the refractive index of air
is the angle of incidence
We can find the value of angle of incidence as follows :

Now again using Snell's law for violet light as follows :

So, the index of refraction of quartz for violet light is 1.47.
