Plane parallel to horizontal plane and parallel to vertical plane Question: A square thin lamina size 25 mm surface parallel to horizontal plane and perpendicular to vertical plane nearest side 10mm above horizontal plane  and 25 mm infront of vertical plane. Draw the projection. Question:  A square thin lamina size 25 mm surface  parallel to horizontal plane and diagonal AC parallel to vertical plane nearest corner 10 mm above  horizontal plane and 25 mm infront of vertical plane. Question: A hexagon thin plate side 25 mm surface parallel to horizontal plane and perpendicular to vertical plane nearest corner/side 10mm above horizontal plane and 25 mm infront of the vertical plane. Draw the projection. Question: A square thin lamina side 25 mm surface parallel to vertical plane and perpendicular to horizontal plane. Draw the projection nearest corner/side to 10 mm above the horizontal plane and 25 mm infront of vertical plane.

                            Diffraction MISSING ORDER When condition for maximum intensity in interference ( double slit) and the condition for minimum intensity in diffraction ( single slit) are simultaneously satisfied then those orders are missing from the spectrum known as missing order. Condition for maximum intensity in diffraction (single slit) Question: Deduce the missing order for a double slit Fraunhofer diffraction, the slit width e= 0.16mm and they are 0.8 mm apart. Ans:  m/n= (0.16+0.8)/0.16= 0.96/0.16 m/n= 6 m= 6n Question: What particular spectra would be absent if the transparencies and the opacities of the grating are equal? Ans: a=e(given) (e+a)/e= m/n 2e/e=m/n m=2n Since, n= 1;2;3;..... m= 2;4;6;....... N-Slit Diffraction Fraunhofer Diffraction by N-slits(grating) Grating- A grating in an arrangement of N number of pa
