1.	Which effect provides direct experimental evidence that light is a transverse, rather than a logitudinal wave motion?A. (a) Light can be diffractedB. (b) Two coherent light waves can be made to interfere.C. (c) The intensity of light from a point source falls off inversely as the square of the distance from the source.D. (d) Light can be polarised.
Answer» Correct Answer - D Sound, a logitudinal wave, can be diffracted, can be made to interfere, whose intensity falls off inversely as the square of distance from the source, but can not be polarised. Light a transverse wave, can be diffracted, can be made to interfere, whose intensity falls of inversely as the square of distance from the source, can also be polarised.
