Homework Statement
Hi guys,
I'm going through a rough time understanding double and single slit and diffraction.
Here's the first problem:
A) A single slit gives destructive interference when m*L=w*sin(theta). A double slit gives constructive interference when m*L=d*sin(theta). Explain the role of d and w for the double and single slit.
B) A very wide slit is narrowed to zero width. When(at what point)does diffraction start to occur?
Homework Equations
A) I guess we can just use the above equations to figure out what their roles are.
B) I was thinking to use a*sin(theta)=m*L
The Attempt at a Solution
A) I don't know how to explain and how those two are related to each other
B) I guess I could say that diffraction starts to occur when a>0, but I'm not sure because it wants a specific point.
Thank you,
Jhonny
