How does the wavelength of light affect the radius of a diffraction disc?

AI Thread Summary
The discussion centers on how the wavelength of light influences the radius of a diffraction disc formed when light passes through a circular hole. It highlights that visible light creates a diffraction disc of 0.1mm, while X-rays, having a shorter wavelength, would produce a smaller diffraction disc. Participants emphasize the importance of understanding the relationship between wavelength and diffraction patterns, suggesting that textbooks or class notes should provide relevant formulas or discussions. The conversation indicates a need for clarity on the principles of diffraction rather than just formulas. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement


Visible light passing through a circular hole forms a diffraction disc of radius 0.1mm on a screen. If X-ray is passed through the same set up, what will happen to the radius of diffraction disc?

The Attempt at a Solution



I'm really clueless regarding this question. I tried to find a formula for radius of the disc but I don't think I need any formulas. Can anyone please help?

What formula do you have that describes diffraction?

Without using formulas, you would need to know in general what happens to diffraction and interference patterns when the wavelength is increased or decreased.

So, your textbook or class notes should either have a formula for diffraction, or have a discussion about diffraction that includes how the wavelength affects diffraction.
 

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...

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...
