Wave optics

Currently Playing: Worked example: Size and Intensity of central maximum | Wave Optics | Physics | Khan Academy

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 Practice this concept - https://www.khanacademy.org/science/in-in-class-12th-physics-india/in-in-wave-optics/x51bd77206da864f3:diffraction-due-to-single-slit/e/diffraction-slit-width-distance?modal=1 Master the concept of Diffraction in a single slit through practice exercises and videos - https://www.khanacademy.org/science/in-in-class-12th-physics-india/in-in-wave-optics/x51bd77206da864f3:diffraction-due-to-single-slit/v/single-slit-interference Check out more videos and exercises on Wave Optics - https://www.khanacademy.org/science/in-in-class-12th-physics-india/in-in-wave-optics To get you fully ready for your exam and help you fall in love with Physics, find the complete bank of exercises and videos for Class 12 Physics here - https://www.khanacademy.org/science/in-in-class-12th-physics-india Khan Academy is a free learning platform for Class 1-12 students with videos, exercises, and tests for maths, science, and more subjects.
