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 ×.

Answer:
x=1
Step-by-step explanation:
3x - 5 =7x -9
Subtract 3x from each side
3x - 5-3x =7x-3x -9
-5 = 4x-9
Add 9 to each side
-5+9 = 4x-9+9
4 = 4x
Divide each side by 4
4/4 = 4x/4
1=x
