I am Shaun job of class 10, I have a doubt in physics on the topic of optics , this is the question Sir,
Can you tell what is the defect of using convex mirrors as rear view mirrors ?, Please explain using ray diagrams , In the video on convex mirrors my teacher says that when an object is very close to the convex mirror there are blind spot's as a ray Comming from that does not reach us, please explain this statement also if you can,Sir,
Is there any way in which we can circumvent this problem,
Thank you for your time Sir

In the introduction of the chapter metal and non-metals there is a subtopic called microscopic world. In the video they are talking about shells surrounding the protons. In my school I am being taught that that the third shell has a valency of 8 but in the video they are saying that the third shell has 18 valency. Please tell me the solution for the same. Thank you.
