For the Tin Man, it was a human heart. For the Scarecrow, it was sharpened intellect. For the Lion, overcoming his fears. For Dorothy, it was to be with her loved ones. For the Witch, it was the ruby slipers (that she never got). And for the Wizard, it was to get past being the benevolent con artist of OZ.
For those who read all the OZ books, it was a great adventure -- into self.
If you were an idiot, you wouldn't have asked. let's get you started with people who can guide you along from the basics to highly advanced material.
Poke around for their "Orbits" software and you'll find a galaxy full, from the very simple to professional material.
Two monochromatic light sources produce a "bell curve" of resonant wavelengths, each generating higher and lower harmonic wavelengths, with the highest amplitude at the midpoint between the two originating wavelengths.
Newtonian Diffraction differs from double-slit diffraction in that the two wavelengths must be within 15% of each other for diffraction to occur. For a bit more detailed analysis, see the link below.

I believe you have some bad information: Truman didn't desegregate the military: he re-imposed racial segregation, replacing Generals Eisenhower and MacArthur because they rejected FDR's racist views, and contrary to the advice of the Joint Chiefs of Staff.
Desegregation was not made a law until Dwight D. Eisenhower prompted it on his first Executive Order in 1953 and then two months later with his first Executive Initiative, which reversed the segregation orders of FDR and HST.
General Eisenhower abolished racial segregation among American forces in Europe as son as he took command in 1942 which infuriated FDR to within a hair's breadth of a stroke.. His Integration Order stood until the end of WWII contrary to the demands of then-president Truman, which nearly ended Eisenhower's career. in the Pacific, General Mac Arthur similarly angered Roosevelt by having Soldiers and Marines of all races serve without distinction.
Admiral Halsey nearly lost his commission because he also refused to implement FDR's racial bias in the Navy.
Harry Truman and Franklin D. Roosevelt were both members of the Klan. Truman's long-time associate, Hugo Black, filibustered fourteen hours to prevent passage of the Eisenhower Equal Education Act. His filibuster ended under protest and the bill passed 83-17 in the Senate and 435-0 in the House.
In 1954, acting in defiance of Eisenhower Equal Education Act, Alabama Governor George Wallace barricaded a Mobile, Alabama, school barring the entrance of black students. Wallace was arrested by FBI and the students registered according to law.
In 1963, Wallace once again proved the racism of Democrats at a Mobile school.
If you look back through history, you will find that Democrats have always been the nastiest of all possible racists, now using tokenism to lay off their historical bigotry.
