Given :
The light rays in the incident ray originate at 20º from the surface.
To Find :
The angle for the incident ray.
Solution :
We know angle of incidence is measured from perpendicular to the surface .
So,
Now, we know by law of reflection :
Angle of reflection = Angle of incident
Therefore, the angle of incident and reflection is 70° each.
The concept that must be applied to solve this problem is that of the magnetic field on Toroid described since the law of Ampere. Mathematically the magnetic field is determined as
Where
= Permeability constant
N = Number of loops
I = Current
r = Radius
As we can see the magnetic field inside a Toroid is NOT uniform, since it is highly proportional to the radius. Which means that as the radius increases the magnetic field decreases.
Therefore the correct answer is: FALSE
