Ray Diagrams

This physics video tutorial on optics provides a basic introduction into ray diagrams. It explains how to draw ray diagrams for converging lens, diverging lens, concave mirrors, and convex mirrors. It explains how to distinguish a real image from a virtual image and how to tell if an image is upright, inverted, enlarged or reduced in size.

the best bet is that he is a clever engineer who knows all that stuff and started a youtube channel to share his knowledge with the rest of the world because I went to engineering school and i can tell you that most of the stuff he talks about like 80 % of it , we take all that in engineering

True, but he’s uniquely good at putting out entire courses of information on all of those things better than most professors who specialize on the individual components can, and in less time.
As, what has always seemed to be, one person.
Truly insane. The amount of time it would take to put out content as often as he has in so many different subjects as well as he does if he doesn’t have a truly incredible gift would be staggering. Idk how he’d be sleeping ever.

How do you know where the focal point goes? For example, for the concave mirrors you put both the focal point and the object on the same side of the mirror, but for the convex mirror, they were on opposite sides of the mirror.

[@puthearathaim2111]

TLDR 'the focus is half the radius', Imagine the spherical mirror being part of a circle, the centre of this circle is the 'centre of curvature' and the focus is located directly on the midpoint between the centre and the intersection between the principle axis (the horizonal line) and the mirror.

3:36 what if the object is at the focal point? What is the location, orientation, size and type of the image created?

[@campbellengel-cartie7372]

You likely already figured this out, but there is no image. This is due to the rays being parallel, having no contact within the lens system.

[@its_me_remember]

@@campbellengel-cartie7372 thank you!!

[@justindonaldson7022]

3:30 shouldn't the second line be drawn from the focal point to the object, not from the center?

[@UpheavaI]

Billy Bob think that is another way, as then you go in a straight virtual line which hits the image point

Inverted?

[@anajuliaglz1485]

why was the last example, the converged lens, a real image?? i though you said that real and virtual image depend if they are on the left or right side of the lens. Wouldn't it be virtual?

[@oyeladewisdom7971]

Can you pls increase the height of the mirrors or reduce the size of the objects, you are making me confuse the path of the focal point

How do u know where the rays are going??

One ray goes paralel to the ground, and the other ray goes through the focal point
