SUMMARY

A reflection grating functions as a diffraction source by altering the angle of the incident beam of light, which results in the separation of light into its constituent wavelengths. The discussion also addresses the feasibility of using a steel ruler as a reflection grating, emphasizing that while it can diffract light, its effectiveness is limited compared to purpose-built gratings. The conversation highlights the fundamental principles of diffraction and the practical applications of reflection gratings in optics.

Can a steel ruler be used as a reflection grating ? if so, why?
 
Why do I get the feeling this is a homework question?
