Question

Elastic waves in solid are

• A. Transverse
• B. Longitudinal
• C. Either transverse or longitudinal
• D. Neither transverse nor longitudinal

Answer 1

Answer: (C)

Either transverse or longitudinal

Elastic waves are normal mechanical waves which need a material medium to travel.

Transverse waves can travel only in solids and only along the surface of liquids, but not in the entire liquid.

Longitudinal waves can travel in all i.e. solids, liquids, and gases.

$\therefore$ $the$ $elastic$ $waves$ $in$ $a$ $solid$ $could$ $be$ $either$ $transverse$ $or$ $longitudinal$ $in$ $nature.$
