Question

As the wind blows across a field of grain, the top of the plants move back and forth when a wave travels across the field. This wave is
a) Transverse wave. c) Longitudinal wave.
b) Polarized wave. d) Electromagnetic wave.

Answer 1

Answer:

longitudinal wave.

Explanation:

longitudinal wave move in the form of rarefraction and compression and hence cause Pwave or pressure wave.

whereas,

Transverse wave travels in the form of crest and trough and hence called S wave or shear wave.

back and forth motion of grain particles is due to longitudinal wave.

Answer 2

Answer:

• longitudinal wave move in the form of rarefraction and compression and hence cause Pwave or pressure wave.
