00:01Parallel rays
00:02Thodee si slant rakhni hai
00:05Yaar agar object agar focus pe hooti hai
00:08To image infinity pe banti hai
00:10Deko mein draw kar raha ho
00:12Now this time
00:13Baut halki si slanting rakhte hai
00:24Yeh raha ray diagram
00:26You may draw very quickly
00:28Bhoati asan bhi hai
00:30Parallel rays
00:32Thodee si slant rakhni hai
00:34Yahaan ke baad
00:36Yeh wali ray to
00:38Yeh yeh toh cd nikal gai
00:40Yeh ray a dash pe
00:42Or yeh wali ray
00:44Ab yeh haas se bend
00:46Karaygi towards the point
00:49Or yeh wali ray bhi
00:51Yeh haan ke baad refract karne ke baad
00:53Bend karaygi apish
00:55And finally converge
00:57Yeh tino rays
00:59A dash pe
01:00Alpha is the angle of slant
01:03Or yeh dash wala point
01:05Jho hai
01:05Voh f naught hai
01:08Objective lens ka f naught
01:10Or eye lens ka bhi focus
01:41Vohin peh hai
02:09Infiniti peh bantii hai
02:09Toh yeh haan donon baat te dekhne ko
02:12Mil gai
02:12Same diagram
02:12At any point
02:13So that means
02:15That means
02:15Final image
02:16At infinity
02:17Now aap yeh way diagram
02:19Jaldi jaldi draw
02:20Kar sakte ho
02:21Or length of telescope
02:22Samajte ho
02:23Length of telescope
02:24Ka matlab
02:25Dono lenses ke bich ka separation
02:29Separating length
02:30Dono lens ke bich ka separation
02:32Jis meh
02:34Jis meh
02:35Is separating distance
02:35Meh sign convention
02:38Nahi apply hooti
02:40Toh siddha
02:41Aap
02:43Distance of separation between both the lenses
02:45Aap f naught plus f e dikhra hai hai
02:50Yeh dekho
02:50See
02:50Yeh raha f naught
02:52Phr plus f e
02:54Is point a dash se aaghe
02:57Sif dho rays ko aaghe badaaya
02:59Third ray ko nahi aaghe badaaya
03:02Kyunki convenient nahi tha
03:03Phir ek or ray
03:05Yeh haan peh aise aajathe
03:06Yeh
03:08Ancha
03:09Oh samaj gaya sir
03:10Yeh chiz yeh haan peh aise aati
03:12Phir ek or ray
03:13Aise karke
03:14Dekhate
03:15Toh yeh two rays
03:17Heh sufficient
03:18Heh
03:19Or yeh dekho bita angle
03:20Yeh haan peh
03:21Jotan
03:22Ten
03:23Yeh magnifying power
03:25Or angular magnification
03:26Is
03:27Beata upon alpha
03:28Phir tan
03:29Beata upon tan alpha
03:30Aise karke start
03:31Karte hai
03:32Beata is concerned
03:33With final image
03:35And
03:36Alpha is concerned
03:37With object
03:38Dono ka angle
03:40Angle
03:40Subtended by
03:41Them
03:42At I
03:43I
03:43R
03:44Beta and alpha respectively

04:41Yes, there are
04:44T
04:46neces
04:48Are
04:51Either
04:51fo plus fe so both fo and fe coincides length of telescope acha ab second wala situation
05:00karengi karena astro normal adjustment wala astronomical telescope pura
05:06i'm now this is second one unlike compound microscope you must have noted objective lens
05:13here in astronomical telescope is bigger and larger or islands is smaller
05:19jabki compound my ultra tha abdekna image at d wale diagram me joki abhi saamne hai this time both
05:28foci coincide nahi karray hai av if not pay image to ban rahi hai intermediate image a dash b dash
05:37but wo point islands ke focus ke andar hai aur phirous ke baal alpha and beta humnay pehle hi
05:45dikha diya this time image is not at infinity kya ki image at d wale raha hai lakin ek or
05:54zabar tas notable point hai ki compound microscope me image was formed sub se piche is side lakin
06:04ye wale image hum log ya haan peh saamne dikha te object ke pehle ye ye ye ray diagram draw
06:12kar pari ya me draw kar ke dikhaun chalo me draw karthau haan peko me draw karthau now this time
06:20o
06:43Beholdt hulkish slanting
06:45Thank you very much.
07:15Thank you very much.
12:00towards us.
12:00You
