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:
Step-by-step explanation:
Perimeter = 2*(length +width)
P = 2*( x+8 + y-1)
P = 2*(x + y + 7)
P =2x + 2y + 17
Answer:
do you have a picture of the problem as well?
Step-by-step explanation:
Answer:
The measure of x = 45 degrees
Angle 1 = 130°
Angle 2 = 124°
Angle 3 = 56°
Angle 4 = 52°
Angle 5 = 72°
Angle 6 = 94°
I primarily used the triangles to get my answers. Remember the angles in a triangle add up to 180°.
