Answer:
There is a dependency relationship between the refractive index of each substance and the radiation wavelength.
The refractive index in a given medium is inversely proportional to the wavelength of a color.
For example:
The rays of the red color have a wavelength greater than the rays of the blue color, therefore they have a lower refractive index and consequently a light scattering less than the blue.
Snell's law :
n₂/n₁ = v₁/v₂ = λ₁ /λ₂
*n: (refractive index)
v: (speed of light propagation)
λ: (wavelength)
Answer: 44 N/m

Finding the interatomic spring stiffness
Because in our model all the bonds are assumed to be the same, the interatomic spring stiffness ks, interatomic is determined by adding the springs . The details of that addition are below, but the final result is that the interatomic spring stiffness is related to the spring stiffness of the wire like so:

Answer:
Diagram A
Explanation:
When an object is travelling in a circular path it has an acceleration called centripetal acceleration, even if it is moving with uniform speed. This acceleration is attributed to the object due to change in the direction of velocity at every instant during the motion.
The direction of the velocity of the object is tangent to the circular path at every instant and if the object beaks free of the circular motion, such as breaking of the string, then it will go in the direction tangent to the circle at that instant. Hence, the diagram that best shows the direction ball will travel is:
