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,
