Two plane mirrors are at right angle to each other. A man stands between them and combs his hair with his right hand. in how many of the image he will be seen using his right hand ? a-1 b-2 c-3 d-none of these
yes our lecture gave us a lot of them and ask us to find answers and tell why to learn much :) and i have searched a lot my last way is here :D
and i just got one law from u :)
see number of images formed = 3 by our last formula and from right hand there will be 2 not sure though
if t was one mirror then one image wii appear and i will be seen using my right hand r ight ?
no, if it would be one mirror we would have seen our left just stand in front of mirror and see
ok if that when we apply that on the mirros there i found two of them is inverted so right hand appears right ?
and one is just like the image in one mirror
can i explain it like that ?
can u draw it please
yes you can but in objective question i don't think you need to draw or explain
i knew we just didn't got the lesson yet that is all question the lecturer ask us to find and learn every possible information so i had to write explanation
|dw:1351705086170:dw| which one of them is right or both are wrong ?
|dw:1351705092375:dw| it will be just one image from right hand i am sure about that
the mirror in the left will show it from right , thanks :)
then this one image. and one on right mirror shows left hand. then where is the third iamge
the third image is at the intersection of mirror that will show from left
then it will appear like one on the right mirror ok ?
yes, so it will be one just one
@experimentX @ghazi ok i guess i get the idea so the last answer is....?
ok what is the name of the formula u told me ?
probably 2 ------------ since there will be 4 images ------------------------ 2 images = direct reflection = 180 turn 2 images = double reflection = 360 turn
it's used for finding the number of images \[\frac{ 360 }{ n }-1\] where n is the angle between two mirrors
@experimentX but that formula will give that 3 images appears ?

i don't say that u r wrong am just confused and i want to understand this one
well ... try imagining yourself. it's pretty late around here .. have to sleep.
i got 2 mirrors, already did that and found three pics and 1 of them shows right hand
@ghazi @experimentX thx for trying to help :)
