The picture on the left represents the reactants in the equation and the picture on the right represents the products. Does this
reaction follow the law of conservation of matter?
• No,there are different kinds of atoms are present in the products as in the reactants.
•No, because there are new products than the reactants.
•No, because there are not the same number of molecules in the product side as in the reactant side.
•yes, the same number and kind of atoms are present in the products as in the reactants.
• No,there are different kinds of atoms are present in the products as in the reactants.
•No, because there are new products than the reactants.

Answer:
a. The refractive index ranges from 1.5 - 1.56
b. 18.7° for violet light and 19.5° for red light.
c. 33.7° for violet light and 35.3° for red light.
Explanation:
a. The refractive index of an object is the ratio of the speed of light in a vacuum and the speed of light in the object.
Mathematically,
The speed of violet light in the object is .
The speed of red light in the object is
Hence, the refractive index for violet light is:
and for red light, it is:
Hence, the refractive index ranges from 1.5 - 1.56.
b. The refractive index is also the ratio of the sine of the angle of incidence to the sine of the angle of refraction.
The angle of incidence is 30°.
The angle of refraction for violet light will be:
And the angle of refraction for red light will be:
The angle of refraction for red light is larger than that of violet light when the angle of incidence is 30°.
c. The angle of incidence is 60°.
The angle of refraction for violet light will be:
And the angle of refraction for red light will be:
The angle of refraction for red light is still larger than that of violet light when the angle of incidence is 60°.
