Radius of diffraction disc

    1. The problem statement, all variables and given/known data
    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?

    3. 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.
