Sir Q1 is wrong as R.I are interchanged . R.I of water is 4/3 and R.I of glass is 3/2 which is written wrong in the question....

Important question of chemistry

Question no. 3 is incorrect

9:41 first question

5ka answer =0.0976

Questions 3 ka detailed answer 👇 Given : n water = 3 4 n glass = 2 3 v glass =2×10 8 m/s n air =1 Speed of light in a medium v medium = n c where c and n are the speed of light in vacuum and refractive index of medium respectively. (a) : v glass = n glass c ∴ 2×10 8 = (3/2) c ⟹c=3×10 8 m/s (b) : v water = n water c ∴ v water = (4/3) 3×10 8 =2.26×10 8 m/s

Q.5. F = 20cm (because the circle of convex lense becomes in the right side) U = -21cm (In any lense and mirrors u is always negative) V = ?? Sol :- 1/f = 1/v - 1/u 1/f + 1/u = 1/v 1/20 + 1/-21 = 1/v (so cross multiple them you will get) 1/20 * -21 1/-420 = 1/v(reciprocate them you get ) V = -420cm Thank me later 😁❤
