1. Crystal edge vs. Solid angle:
- Crystal edge: A crystal edge refers to the boundary or intersection between two crystal faces or facets. It is a linear feature that defines the shape and structure of a crystal. Crystal edges are typically straight and can be measured in terms of length.
- Solid angle: A solid angle, on the other hand, is a three-dimensional angle that measures the amount of space or solid substance that a cone or pyramid-shaped region occupies in space. It is measured in steradians and is used to describe the extent of a solid object's influence or coverage in three dimensions.
2. Measurement:
- Crystal edge: Crystal edges are measured in terms of length, typically in units such as millimeters or angstroms. The length of a crystal edge can be determined using specialized tools such as a goniometer.
- Solid angle: Solid angles are measured in steradians, which are a unit of measurement for solid angles in three-dimensional space. One steradian is equal to the solid angle subtended at the center of a sphere by a portion of the surface area equal to the square of the radius of the sphere.
3. Representation:
- Crystal edge: Crystal edges are represented as straight lines connecting two crystal faces or facets in a crystal structure diagram. They help define the overall shape and symmetry of the crystal.
- Solid angle: Solid angles are represented as a cone or pyramid-shaped region in three-dimensional space that extends from a point or vertex. They are used to describe the extent of coverage or influence of a solid object in three dimensions.
In summary, the main differences between crystal edge and solid angle lie in their definitions, measurements, and representations. Crystal edges are linear features that define the boundaries between crystal faces, while solid angles are three-dimensional angles that measure the extent of coverage or influence of a solid object in space.

Crystal edge and solid angle are two different geometric concepts that are often used in crystallography and solid state physics.
Crystal edge is a line formed by the intersection of two crystal faces. It is a one-dimensional object that separates two crystal faces.
Solid angle is a two-dimensional object that measures the amount of space that is enclosed by a set of lines or surfaces. It is a measure of the "spread" of a set of lines or surfaces.
The main differences between crystal edge and solid angle are:
- Dimensionality: Crystal edge is a one-dimensional object, while solid angle is a two-dimensional object.
- Shape: Crystal edge is a line, while solid angle is a cone-shaped object.
- Measurement: Crystal edge is measured in units of length, while solid angle is measured in units of steradians.
In crystallography, crystal edges are often used to describe the symmetry of a crystal. The number and arrangement of crystal edges can be used to determine the space group of a crystal.
In solid state physics, solid angles are often used to describe the scattering of light or particles from a crystal. The solid angle of scattering can be used to determine the structure of the crystal.
