The document summarizes key concepts from a chapter on refraction and lenses, including how light changes speed and direction when passing through different materials. It explains refraction through Snell's law, total internal reflection, lenses, dispersion, and applications like mirages and rainbows. Concepts are defined and examples are provided to illustrate refractive principles and their practical uses.
Physics ( human eye and the colourful world).Nikhil Dahiya
ppt on human eye and its structure. shows different parts of the eye . helps the student to learn about the eye more breifly.it is a science ppt which will be helpfull . teachers can also take it in the us for letting the students understand better .
Here is another creative presentation by your slide maker on the topic "Refraction through lenses". Hope you like it. If you like it then please *like*, *Download* and *Share*.

Most of the times this study confused me...so, i just put some important points in one place to easily keep them in mind..hope it will help other students as well..and inform me, if a reader find anything new to improve it further.
Use principles of reflection and refraction to describe how lenses and mirrors work.

Reflection of light in spherical mirrorMUBASHIRA M
this slide contains laws and terms of reflection of light. especially the image formation and ray diagrams of spherical mirror that are mainly useful for science students
This topic seems difficult to make a ppt on! But I hope this helps :) Feedbacks or any tips are welcomes. All the best for the presentation or your exam!

To know that sound can be reflected, refracted, diffracted, and produces interference effects.
Know that sound is a wave because it can be reflected and refracted as with particles, diffraction and interference only occur with waves
as a partial requirement for one of my subject for this semester
I would like you to view my presentation and comment as well
I will be very glad if you find my presentation interesting, or comment on how I can improve my craft, THANK YOU :)
This paper shows my findings for determining the grating constant of a diffraction grating, the wavelengths of each line of the spectrum of hydrogen, and experimentally calculating the Rydberg constant.
