Hello,
I am working on the exercises of the geometry of the prism from the optics(Essentials), and I don't understand how angle A is equal to the sum of the angles r1 and r2 in every single exercise. When I tried using the hints, this was not explained there. Could you please explain that?
This link takes you to the exercise:
Thank you for your assistance and care!
Do you have a specific example? Have you looked at this video: https://youtu.be/3d2C-pDkTEg
I just resolved my doubts by rewatching the following video at minute 4:00: https://www.khanacademy.org/science/optics-essentials/x0484cce4552ac2a3:how-do-rainbows-and-halos-form-in-the-sky/x0484cce4552ac2a3:how-do-rainbows-and-halos-form/v/deriving-prism-formula. Thanks for asking though!
Your link led me to an interesting Newton's Prism experiment! Thanks for suggesting that video!
I hope you have a wonderful rest of the week!
