I am doing my science 10 by correspondence and I came upon a question that puzzles me. Why are modern light microscopes called Compound microscopes. That and How would I "determine theactual size of the cells shown in the illistration if the field diameter measures 2.2 mm"??? ...

Science Question Take 2
Sorry, my last post got cut off. Here it is again: For my science homework this weekend, I have to write a paper on how crystals absorb and focus the etheric energies of the sun and how they can be used by adepts for the good of mankind. I am having trouble finding scientific ...

Why do windows act like mirrors at night? What is the science of the windows that you can see out of but when you look into it is all blurry and dark?

1. Correct. False. Convex mirrors do not form real images of real objects. 1/20 + 1/di = -1/10 1/di = -3/20 di = --6.7 (behind the mirror, demagnified. 2. You left out the position of the object. If the object is outside 10 cm, the image is real and inverted. If the object is ...

1. I didnt say anything about concave mirrors. THe question was on lenses. There are two types: concave (diverging), and convex (converging). If concave lenses produce only virtual images, what does that imply about convex? Here is my previous brief response to the same ...

What are convex mirrors?
Thursday, September 25, 2008 at 1:38pm by Mariz
Convex mirrors bulge out in the center, while concave mirrors are depressed in the center. I hope this helps. Thanks for asking.

SCIENCE: GR.10 OPTICS CONVEX MIRRORS
A convex security mirror has a focal length of -0.25m. A person with a height of 1.5m is 4m from the mirror. calculate the image distance and image height. AND An object 0.4m tall is placed 2.5m in front of a convex mirror that has a focal length of -90cm. Calculate image ...

SCIENCE: GR.10 OPTICS CONVEX MIRRORS
In each case use the mirror formula 1/do + 1/di = 1/f do = object distance di = image doistance Make sure you use negative f for the convex mirrors. The image height is di/do times the object heeight.

That is a subject in physiological optics or "ocular physiology", in which I am not an expert. A common example is the eyes' getting adapted to the dark (and more sensitive) after being in darkness for about a half hour. See http://en.wikipedia.org/wiki/Adaptation_(eye) for an...

The mirror is concave (convex mirrors can only produce diminished images ) Image distance 1.27•23.5 =29.85 cm. 1/f = 1/di -1/do 1/f = 1/ 23.5 – 1/ 29.85 = 0.0091 cm f = 109.9 =110cm = 1.1 m R =2•1.1 = 2.2 m

1/do+1/di=1/f is the equation, solve for di. then, having di (remember the sign conventions for convex mirrors), M=-di/do=hi/ho
