In a single slit experiment, the width of the slit is doubled. Which one of the following statements is correct?
A
The intensity and angular width of the central maximum are unaffected.
B
The intensity remains same and angular width becomes half.
C
The intensity and angular width both are doubled.
D
The intensity increases by a factor 4 and the angular width decreases by a factor of 
.
.
Text Solution
Verified by ExpertsThe correct answer is:
D
: 
So, when slit widths doubled, intensity is increased 4 times and 
(angular width) becomes half as
