A light source, which emits two wavelengths 1=400 and 2=600 , is used in a Young’s double slit experiment. If recorded fringe widths for 𝜆𝜆1 and𝜆𝜆2 are𝛽𝛽1 and © number of fringes for them within a distance yon one side of the central maximum are m1 and m2, respectively, then (A)2>𝛽𝛽1 (B)𝑚𝑛𝑛1>𝑛𝑛2 (C) From the central maximum, 3rdmaximum of λ2 overlaps with 5th minimum of λ1 (D)The angular separation of fringes for λ1 is greater than λ2 2. Heater of an electric kettle is made of a wire of length L and diameter d. It takes 4 minutes to raise the temperature of 0.5kgwater by 40K. This heater is replaced by a new heater having two wires of the same material, each of length L and diameter 2d.The way these wires are connected is given in the options. How much time in minutes will it take to raise the temperature of the same amount of water by 40 K? (A)4 if wires are in parallel (B) 2 if wires are in series (C)1 if wires are in series (D)0.5 if wires are in parallel JEE Advanced entrance exam sample question paper      For the question paper , here is the attachment |
