The concentration of a sugar solution can be determined by:
Correct answer: B. Plane polarized light
- A. Un-polarized light
- B. Plane polarized light
- C. Interference of light
- D. Diffraction of light
Explanation
The concentration of a sugar solution can be determined using a technique called polarimetry, which involves the use of plane-polarized light. When plane-polarized light is passed through a sugar solution, the plane of polarization of the light is rotated by an amount that depends on the concentration of the sugar in the solution. The plane of polarization of the light is rotated by an angle θ as it passes through the sugar solution. By measuring the angle of rotation and knowing the specific rotation of the sugar, the concentration of the sugar in the solution can be determined. Therefore, the correct option is B) Plane polarized light.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
