A \(475 \mathrm{~nm}\) wavelength laser produces a diffraction pattern using a diffraction grating of slit spacing D. What is the range of values D can have that will produce exactly 15 bright spots on a screen \(10.0\) meters away.

An experiment is set up, as shown below, to investigate the effect of slit width on the degree of diffraction. In \(\triangle A C E, A B=B C, G E=15 \mathrm{~cm}\) and \(A F=F E=E D\). Determine the length of \(C E\). In the sketch $\mathrm{A}(2 ; 3)$ and $\mathrm{B}(-1 ; 6)$ lie on the circle with midpoint $\mathrm{M}(\mathrm{c} ; \mathrm{d})$ $M$ is also a point on the line given by $2 x+5 y+$ $1=0$

\(D M\) is a diameter of circle \(A . R T D \perp R C\), \(R T=3 \mathrm{~cm}, R C=4 \mathrm{~cm}, M C=6 \mathrm{~cm}\) and \(D M=2 x\). The sketch below shows the grpahs of $f(x)=2x+3$ and $g(x)=-2x^2+14x+k$. C is any point on $f$ and D any point of $g$, such that CD is parallel to the y-axis. k is the value such taht C lies above D.
