When light passes from one medium to another at an angle, it may refract, or bend, according to Snell's law:
n₁sin(θ₁) = n₂sin(θ₂)
n₁ = index of first medium, θ₁ = angle of incidence, n₂ = index of second medium, θ₂ = angle of refraction
Given values:
n₁ = 1.33 (water), θ₁ = 45.0°, θ₂ = 40.3°
Plug in and solve for n₂:
1.33sin(45.0°) = n₂sin(40.3°)
n₂ = 1.454
I looked up this value on the HyperPhysics indices of refraction table... The index we calculated is closest to 1.46, which is that of fused quartz.
Answer:
Explanation:
Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. Scientific and technological innovations mean that we are improving our efficiency at using and harvesting natural resources.
