Answer:
30.81°
Explanation:
θ₁ = angle of incidence = 50°
θ₂ = Angle of refraction
n₂ = Refractive index of glass = 1.5
n₁ = Refractive index of air = 1.0003
From Snell's Law
Using Snell's law as:


Angle of refraction= sin⁻¹ 0.5122 = 30.81°.
Answer:
The magnetic energy density is 
Explanation:
From the question we are told that
The earths magnetic field is 
Now

=> 
So


Generally the magnetic energy density is mathematically represented as

Here
is the permeability of free space with a constant value

substituting values for equation above


Sometimes in the same direction but most of them go in the opposite direction
