WebFor a diffraction grating, the relationship between the grating spacing (i.e., the distance between adjacent grating grooves or slits), the angle of the wave (light) incidence to the grating, and the diffracted wave from the … WebA reflection grating can be made by cutting parallel lines on the surface of refractive material. Gratings that have many lines very close to each other can have very small slit spacing. For example, a grating ruled with 5000 lines/cm has a slit spacing d=1/5000 cm=2.00×10-4 cm. A section of a diffraction grating is illustrated in the figure.

WebHence the angle adjoining the screen in the isosceles triangle about which you are talking will become very small. The other two angles are equal ( a property of isosceles triangles) and each will be approximately equal to 90 degrees since the sum of all the angles in a triangle must be equal to 180 degrees ( and the third angle is very small).
