All the Best! 1 / 10 In a polarimeter, optical rotation depends on Length of the polarimeter tube only Concentration of solution only Both length and concentration None 2 / 10 A point on screen has path difference = λ/4; resultant amplitude = 0 A A√2 A√(2 + √2) 3 / 10 Huygens’ principle states that every point on a wavefront acts as A primary source A secondary wavelet source A particle emitter A point of reflection 4 / 10 Colours of thin films in soap bubbles arise from Dispersion Diffraction Interference Polarisation 5 / 10 Resolving power of optical instrument increases with Increasing λ Decreasing aperture Increasing aperture Increasing distance 6 / 10 Angular resolution of telescope limited by Reflection Polarisation Diffraction Refraction 7 / 10 Two polaroids crossed at 90°. Intensity through them = I₀ I₀/2 I₀/4 0 8 / 10 Brewster’s angle is the angle at which Reflection = Refraction Reflected & refracted rays ⟂ Both have same speed Refracted light vanishes 9 / 10 When a Polaroid is rotated by 360°, transmitted intensity Constant Zero Doubles Changes periodically 10 / 10 When polarised light passes through analyser, intensity becomes zero if angle between planes is 0° 45° 90° 60° Your score is 0% Restart quiz
