When a beam of light is passed through a colloidal solution, it gets -
(A) reflected
(B) absorbed
(C) scattered
(D) refracted
Time taken by the laser beam to return to Earth after reflection from the Moon = 2.56 s Speed of light = 3 × 108 m/s Time taken by the laser beam to...
1 Answers 1 viewsWhen beam of light was passed through beaker A containing true solution, path of light was not visible. But when it was passed through beaker B (colloidal solution), the path...
1 Answers 1 viewsThe correct answer is (c) λ`< λ EXPLANATION: Since the reflected wave is inverted, the pulse is traveling from the lighter string to heavier string. Hence the speed of the incident...
