| Q. |
Which of the following phenomenon helps to conclude that light is a transverse wave? |
| A. | interference |
| B. | diffraction |
| C. | polarization |
| D. | refraction |
| Answer» C. polarization | |
|
Explanation: The phenomena of interference and diffraction of light were successful beyond doubt to prove that light is a form of wave. But they failed to decide whether light is transverse or longitudinal wave. The fact that light is a transverse wave was established only after the discovery of the phenomenon of polarization. |
