Unadopted amendments to the Bill of Rights

ven, 2018-09-14 20:27
The original draft of the Bill of Rights had twelve amendments, not ten! What were those unadopted amendments? In this video, Kim discusses the unadopted amendments with scholar Fergus Bordewich. To learn more about US Government and Politics, visit Khan Academy at https://www.khanacademy.org/humanities/ap-us-government-and-politics To read more about constitutional law, visit the National Constitution Center’s website: https://constitutioncenter.org On this site, leading scholars interact and explore the Constitution and its history. For each provision of the Constitution, experts from different political perspectives coauthor interpretive explanations when they agree and write separately when their opinions diverge.

Structure of human eye

mer, 2018-09-12 00:23
Let's explore the major parts of our eye, and see what each one does. Created by Mahesh Shenoy

Convex mirror & applications

mer, 2018-09-12 00:23
When curved mirrors have a reflecting surface on the outside, they are called convex mirrors. (vex stands for bulging out). Let's learn what they do and their applications in our day to day life. Created by Mahesh Shenoy

Why do stars twinkle (but planets don't)?

mer, 2018-09-12 00:23
Let's explore what causes the twinkling effect of stars. We will also explore why planets, sun and moon don't seem to twinkle. Created by Mahesh Shenoy

Spherical & parabolic mirrors

mer, 2018-09-12 00:23
In this video, we will explore two kinds of curved mirrors, parabolic and spherical mirrors. Created by Mahesh Shenoy

Magnification formula for mirrors

mer, 2018-09-12 00:23
Let's explore how to calculate image height and it's nature (real or virtual) using magnification formula Created by Mahesh Shenoy

Power of lens

mer, 2018-09-12 00:23
Power is an incredibly useful quantity when it comes to lenses. Let's find out what it is and where it is used. Created by Mahesh Shenoy

Newton's prism experiment

mer, 2018-09-12 00:23
Let's explore how Sir Issac Newton experimentally proved that white light is made of all the colours of the rainbow. Created by Mahesh Shenoy

Mirror formula

mer, 2018-09-12 00:23
Let's explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams Created by Mahesh Shenoy

Presbyopia

mer, 2018-09-12 00:23
Let's explore what are the symptoms and causes of Presbyopia. We will also see how bifocals correct them. Created by Mahesh Shenoy

Concave mirrors

mer, 2018-09-12 00:23
In this video, we will see how concave mirrors focus a parallel beam of light to a single point. Created by Mahesh Shenoy

Solved example on lens formula

mer, 2018-09-12 00:23
Using lens formula can be tricky because we need to substitute using signs. In this video, we will take one example and discuss how to use the lens formula. Created by Mahesh Shenoy

Sign conventions for mirror (& lenses)

mer, 2018-09-12 00:23
Let's explore the sign conventions (rules to assign +ve and -ve values) we use for mirrors and lenses. These rules are called Cartesian sign conventions Created by Mahesh Shenoy

Lens formula

mer, 2018-09-12 00:23
Let's see how to use lens formula (1/v-1/u= 1/f) to locate images without having to draw ray diagrams. Created by Mahesh Shenoy

Magnification formula for lenses

mer, 2018-09-12 00:23
Let's explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it's real or virtual) Created by Mahesh Shenoy
