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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
