Answer:
The reflectivity at the boundary of the two grains is ×
Step-by-step explanation:
Given :
Refractive index of one grains () = 1.553
Refractive index of second grains () = 1.544
According to the fresnel equation,
∴ general equation of refraction ( reflectivity )
where = incident angle,
= transmitted angle
but for normal incidence °
so our equation become,
⇒
×
Therefor reflectivity at the boundary is given by ×
