Sign conventions for mirrors and lenses

Posted by Deepak Gawri 2 weeks, 6 days ago

CBSE > Class 10 > Science

1 answers

Md Rashid Ansari 2 weeks, 5 days ago

Since, the center of curvature and focus lies behind the convex mirror, signs of the radius of curvature and focal length are taken as + (positive) in the case of the convex mirror. In the case of a convex mirror, images are always formed behind the mirror, thus the distance of the image is taken as positive. Focal length of a convex lens is positive. Whereas focal length of a concave lens is negative, according to the sign convention. Because the object is always on the lens's left side, the incident light always moves from left to right.

Hi! Let me explain this. Bowman capsule-It is just cup like structure which is full of arota which is red in colour their capilaries present in the bowman capsule which is also known as (dirty blood) helps to filtrate red blood only. Glomerulus(singular) Glomerul(plural)-red that part which is red in colour known by this which is present in bowman capsule helps to blood filtrate.Also it leaves some but heavy blood molecule can able to go eg-blood other waste get contaminated below the bowman capsul this is know an Flitrate(it contains WBC,ammonia,uric acid,etc.). Tubule-it is a cup like structure which is present below the bowman capsule it is attached to bowman capsul .Filtrate blood travel thqrough in it and goes to branch of uretur. Capilaries around tubule helps to arota blood to vein blood which help to carry clean blood and som of waste material go into tubul and get with waste material go in uretur. This is your answer.
