Question

(a) If the fourth-order maximum for monochromatic light falling on a double slit is at an angle of 24.9°, at what angle in degrees) is the seventh-order maximum? o x (b) What is the angle (in degrees) of the sixth minimum? o (c) What is the highest-order maximum possible here?

Answer 1

a) d sing=no forn o = 24.99 =) d Sin 24,90=4d Now for n=7 d Sino=70 2) =) Sinagog Sino 7 =) 8= Sintl (7 sin 24.9%) = 47.469

b) For Sinth minima d sino 5+1 for sinth order minima n=5 =) Sino=112 d from eq 0 => 6= Sin "[10* 1. Sin 24.907 - 35.37 c) . dsino VW= =) am= m= d sino P for maman ما را ن 9.6 d Sino= Sin 24.9° =) m=9
