Let's solve a couple of questions on the size and intensity of central maxima in single-slit diffraction!

00:00 1st question
00:24 What is the size of the central maximum?
01:39 What is the angular width of the central maximum?
02:16 Condition for destructive interference in a single-slit diffraction
03:09 Deducing change in angular width of central maximum
04:06 Deducing change in the size of central maximum
05:55 2nd question
06:18 Intensity proportional to the square of the amplitude
07:41 Deducing change in intensity when the width of the slit is increased
