Answer:
n = 1.4266
Explanation:
Given that:
refractive index of crystalline slab n = 1.665
let refractive index of fluid is n.
angle of incidence θ₁ = 37.0°
Critical angle
According to Snell's law of refraction:
At point P ;
Therefore:
Then maximum value of refractive index n of the fluid is:
n = 1.4266
Answer:
Part a)
Part b)
Explanation:
Part a)
Since the diver is moving under gravity
so here its acceleration due to gravity will be uniform throughout the motion
so here we will have
here we have
Part b)
at highest point of his motion the final speed will be zero
so we will have
