Resolution Definition and 313 Threads

Dispute resolution or dispute settlement is the process of resolving disputes between parties. The term dispute resolution is sometimes used interchangeably with conflict resolution, although conflicts are generally more deep-rooted and lengthy than disputes. Dispute resolution techniques assist the resolution of antagonisms between parties that can include citizens, corporations, and governments.

    Increase in numerical aperture leads to a decrease in line width?

    According to the formula, an increase in numerical aperture leads to a decrease in minimum line width and thus better resolution. However, if were to draw it out, given the same depth of focus, why does the minimum line width increase with higher numerical aperture?

    Ruler measurements and knowing how many decimal places to include

    I teach high school and am trying to put together a resource that teaches students how to measure lengths properly with a ruler or meter stick. They don't understand how many decimal places to include in their answer (i.e. they will often write 1.7 cm when it should be 1.70 cm), and they...

    Condition for resolution of two point sources of light

    The formula is ##\theta=1.22 \frac{\lambda}{b}## where b is the diameter of circular aperture I thought it would be ##\theta \geq 0.61 \frac{\lambda}{r}## since diameter = 2 x radius but the answer is (D) Do we just consider ##r \approx b## since maybe it is small or am I missing something...

    Do I have choice what resolution to stream using boxes like Roku?

    Hi Sorry about the stupid question. I am completely green on tv streaming. I have a limitation of 25MBPS internet connection. I know 4K video needs 25MBPS speed. That is I can ONLY run one tv. I really don't care about the clarity and resolution. I have modern smart tv, but I am still feeding...

    A MCP Detector Resolution: Gaussian vs Uniform Distribution

    Hello! If I want to model the time and spatial resolution of an MCP detector, should I use a gaussian or a uniform distribution? I imagine that, for example for the spatial distribution, the uncertainty is given by the size of the pixel on the detector, which makes me think that uniform...
