Solving Diffraction Grating Angle: Can it be 90°?

AI Thread Summary
The discussion centers on whether the angle in a diffraction grating can be 90 degrees. The relevant equation, d sin θ = nλ, suggests that it is theoretically possible for the angle to reach 90 degrees. However, participants express uncertainty about the implications of such an angle, particularly regarding the location of the maximum. The conversation highlights the need for clarity on how diffraction patterns behave at extreme angles. Ultimately, the feasibility of a 90-degree angle raises questions about the observable outcomes in diffraction experiments.

You know when you have diffraction gratings, you have to measure the angle between center and first order/maxima right? My question is: can the angle be 90°? Or is it always less than that?
d sin θ = nλ

Thank you!

Hi tenzinlhazey and welcome to PF

:welcome:

According to the equation, the angle can be 90o. If that were the case, where would the maximum appear?

Aww thank you :) yes, I m not sure where would the maximum appear. :/

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
