Hi everyone and welcome back to Educator.com. 0000
In this mini-lesson, we are going to go through page 1 of the worksheet on refraction from the APlusPhysics site. 0003
And you will find the link to that down below the video. 0009
Now as we go through these questions, we are not going to go through 2-4 here in our review, just because they are -- the do not lend themselves well to doing these on video with the requirement for a protractor and drawing things to scale, so I will let you guys do those on your own. 0012
In which way does blue light change as it travels from diamond into crown glass? 0031
Well to do this one, you need to know that the index of refraction of diamond is 2.42 and the index of refraction of crown glass is about 1.52, so those would be good things to look up beforehand or to use a table to look up. 0035
What happens as you go from high index to low index materials? 0049
Now, on to Number 5 -- A change in the speed of a wave as it enters a new medium, produces a change in -- well V = F(λ) and as the wave enters a new medium, frequency stays the same, so a change in the speed is going to produce a change in the wavelength. 0062
The book features an effective, 5-step plan to guide your preparation program and help you build the skills, knowledge, and test-taking confidence you need to succeed. This fully revised edition covers the latest course syllabus and matches the new exam. It also includes access to McGraw-Hill Education’s AP Planner app, which will enable you to customize your own study schedule on your mobile device. It includes a full-length practice AP Physics 1 exam and 3 separate study plans to fit your learning style.
This book is written by our very own Professor Fullerton and features more than 600 worked-out problems with full solutions and deeper understanding questions. AP Physics 1 Essentials covers all major topics included in the AP Physics 1 course, including: kinematics, dynamics, momentum, impulse, gravity, uniform circular motion, rotation, work, energy, power, mechanical waves, sound, electrostatics, and circuits.
