Answer:
The index of refraction of the liquid is 1.35.
Explanation:
It is given that,
Critical angle for a certain air-liquid surface,
Let n₁ is the refractive index of liquid and n₂ is the refractive index of air, n₂ =1
Using Snell's law for air liquid interface as :
So, the index of refraction of the liquid is 1.35. Hence, this is the required solution.
Answer:
According to the answer, the speed of light is being achieved.
Explanation:
The velocity of the light is:
Where E = energy = 3.03x10⁻¹⁹J
P = momentum = 1.01x10⁻²⁷kgm/s
Replacing:
