No need to use the word grounded as past participle of grind. Just ground is enough.
Out of three rectangular faces we need only two faces. The third face is not needed.
More over as we observe the emerging light there would be two sets of waves coming from the two transparent faces. This would certainly disturb the experimental determination. Hence we have to grind any one of the three.

How many fewer faces does a rectangular prism have then a pentagonal prism?
A rectangular prism has 6 faces. A pentagon prism has 7 faces. Therefore a rectangular prism has one less face than a pentagonal prism.
Which 3D shapes has five faces?
Triangular prism is one and another one is the rectangular prism
What are the plat surfaces on a pyramid cube or rectangular prism called?
The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
What is the property of a hexagonal prism?
It has two congruent hexagonal faces that are parallel to one another and six rectangular faces joining these together. A hexagonal prism has 8 faces, 12 vertices and 18 edges.It has two congruent hexagonal faces that are parallel to one another and six rectangular faces joining these together.

What are the flat surface on a pyramid cube or rectangular prism called?
faces every polyhedron has one

Why are the flat surfaces on a rectangular prism called faces?
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.

Does a triangular prism has 3 rectangular faces?
Short answer, yes. Long answer, a triangular prism has two triangular faces, its bases, and three rectangular faces, its sides, which connect the two faces. Unfolding the prism into a net reveals a rectangle divided into three rectangular sections (these are the three rectangular faces) and two congruent triangles attached along a common edge to one of these rectangles (these are the two triangular faces).

Is a prism a pyrimid?
No. A prism has one face which is an n-sided polygon and n triangular faces meeting at a point whereas a prism has two m-sided polygonal faces, and m rectangular faces joining them.
What is one of the faces of a rectangular prism?
4 of the faces will be identical rectangles and 2 will be slightly different identical rectangles.
What is a triangular prism with a slanted top called?
A triangular prism that is sitting on one of its rectangular faces MUST have a slanted top!
6 rectangular faces 12 edges and 8 vertices?
> A cube. Actually, any rectangular prism has 6 rectangular faces, 8 vertices, and 12 edges. A cube is just one possibility.
What figure has one rectangular face and two pairs of congruent triangle faces?
