Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
Our site contains 6 navigation areas. The Primary, Secondary,
and Page Level navigations have a screen reader version of their nav
structure that allows using the left and right keys to navigate sibling
navigation items, and up or down keys to navigate parent or child
navigation items. The others can be navigated using tabs.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
While not every area of
Physics Classroom is usable purely from keyboard and screen reader, we
are committed to continue work on making this possible. If you have
questions or need additional help, please use

L1.
Score
_____
Included, labeled and organized all parts of the lab report.
_____ / _____
_____
Data section includes the provided diagram; nodal and antinodal lines were traced and labeled with an m number. Specific nodal and antinodal points were selected and labeled with a letter; measurements from these points to the two sources (in terms of l) are recorded in the provided data table. Path difference values are recorded (in terms of l) as well.
_____
Conclusion states the equations relating the path difference to the wavelength for nodal and antinodal points. Symbols used within the equation are defined. Equations are accurate and clear.
_____
Discussion of Results describes the evidence leading to each of the equations in the Conclusion section. Specific trials are referenced and discussed to provide evidence for the equation.

Score
_____
Included, labeled and organized all parts of the lab report.
_____ / _____
_____
Data section includes the provided graphic and the completed table. Calculations of wavelength are accurate; work is clearly shown for the two methods.
_____
Conclusion/Discussion describes the results of the analysis and compares the effectiveness of the two methods (equations) in calculating the wavelength. The more accurate method should be identified; evidence to support this conclusion is intelligently discussed.
