    Grating Reflection
AI Thread Summary
Reflection gratings function as diffraction sources by altering the angle of the incident light beam, which causes the light to spread into various directions based on wavelength. A steel ruler can be used as a reflection grating due to its finely spaced edges that can diffract light, although it may not be as effective as specialized gratings. The discussion hints at the educational context, suggesting that the questions posed may stem from a homework assignment. Understanding the principles of diffraction and the role of angle in light behavior is crucial for applications in optics. Overall, the mechanics of reflection gratings are essential for manipulating light in various scientific and practical applications.

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

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
