Please tell me what I need to know and what equations I need to use for these type of problems. Please define the variables in the equations too. Thanks.(adsbygoogle = window.adsbygoogle || []).push({});

-Sketch or identify the intensity patteren that results when monochromatic waves pass through a single slit and fall on a distant screen, and describe how this pattern will change if the slit width or the wavelength of the waves is changed and Calculate for a single-slit pattern, the angles or the positions on a distance screen where the intensity is zero.

What is intensity? Is it where the maximas (bright frindges) are? Is there zero intensity where there is a minima (dark fridge)?

I don't know if this is the right equation to use for the objective above:

[tex]sin \theta_{dark}=\frac{m\lambda}{a}[/tex]
