[@AnamtaKhan-qs9mu]

a) n = c/v
b) Light travels fastest in medium B
c) 1.2
d) i > r
e) 1/2

Pehle batayi new profile pic kaisi lagi 😅😅 koi aur nhi main hi hoon
Hw ans : Bhaiya question nhi diya hai us slide pe bas absolute refractive indixes de rakhe hain😂😂😂😂
Also thank you I am glad aapko rakhi pasand aayi ❤❤
Session was awesome. Ab darr khatam aur practice karungi to darr khud dur bhag jayega 😂😂😂
Btw aapke study tips mujhe dewana bana rhi hai ❤❤
Also main vegetarian hun (krishn consious) hun chicken ka naam mat lo yaar😅😅

[@preethaprakash7667]

Home Work answer ( my teacher gave same hw😁)
(a) n = c/v
The absolute refractive index is directly proportional to speed of light in air and inversely proportional to speed of light in a given medium.
(b) Medium B ( Speed of light in medium b will be faster cuz refractive index is low )
(c) 3*10^8 / 2.25 * 10^8 = 1.33
(d) Absolute refractive index of a medium is defined as the ratio of velocity of light in vacuum to the velocity of light in the medium. n=c/v

30:05 sir merko bhi laga ki 3.6 kaise aagya yr mai apna 5 minute se dekh rha hu ans fhir Maine dekha ki water ki toh 4/3 hoti ye kya hogya.....lekin maine 1:36 sec mai kr liya tha pura sahi karke value thank sir.... ❤

Sir take care or ap apne health ka dhyan rakhna ❤🔥

Sir Balle Balle
Question me to kuch nahi pucha hai
Agar A,B,C,D meterial ka name hai ans to
- Ruby , Water, Dimond, dense flint glass,
❤️❤️❤️

Homework Answer :-
(a) vμ=c
(b) In medium B light travels fastest
(c) Refractive index of A - 1.2
(d) When light travels from air to glass,
angle of incidence > angle of
refraction
(a) refractive index of Q with respect
to P is 0.5
By mirror formula,
1/v + 1/u = 1/f
⇒ 1/v = 1/f - 1/u
⇒ 1/v = 1/-20 - 1/-30 = 1/-20 + 1/30 = -3+2/60
= -1/60
⇒ v = - 60 cm
Finding Image distance when the object
is at C,
u = C = 2f = 2 x 20 = (-) 40 cm
f = -20 cm
By mirror formula,
1/v' + 1/u = 1/f
⇒ 1/v' = 1/f - 1/u
⇒ 1/v' = 1/-20 - 1/-40 = 1/-20 + 1/40 = -2+1/40
= -1/40
⇒ v' = - 40 cm
∴ Required difference = (-60) - (-40) = -60 +
40 = (-) 20 cm
Answer can be either in negative or positive.
Sir Please complete Human eye chapter before 10 September.

Kina sahi question tha ne ye interesting .......... ❤
Bese sir kash ye Boards me aaye ye hi likhna hai bilkul same
Ladoo sawal tha
Sir mujhe ye baat batao ke : mera BUDBAK net is hi time pe BUDBAK PANTHI dikhata hai matlab nahi chalta hai to fir ap apne session ko thoda phale karne me agar comfortable ho tab hi ap karna nahi to bata dena 🤧kiyu ki apko problem nahi hone chaye 😌
