Homework Answers
a) For angle =30°
23) Relative intensity given is- 0.06
24) The two arrows are located at 30° on intensity profile. Means on interference pattern,the arrows will be at-
For minima, d sin
= (k-1/2) 
Putting values and solving for k,
k=2.
Yes,intensity can be find from this. The intensity at second minima is less than that observed at central maxima.
b) Angle=50°
25) Relative intensity=0.063
26) By using same formula as in 24,
k = 3 .
The arrows are located at 3 rd minima. The intensity can be found from this. Its less than central maxima.

1. The picture below shows the intensity as a function of angle (in degrees) for a 2-slit interference pattern. You can assume that the gridlines are spaced by 1 degree on the horizontal axis. a. Assuming we are using 633 nm laser light, what is the approximate slit spacing? b. Recall that the 2-slit intensity pattern is pinched to zero by the diffraction pattern created by the slit width. Approximately how wide are the slits? asin θ ηλ gives the...
