The type of waves that can be propagated through solids is:

$Assertion :$ When a beetle moves along the sand within a few tens of centimeters of a sand scorpion,the scorpion immediately turns towards the beetle and dashes towards it.
$Reason :$ When a beetle disturbs the sand,it sends pulses along the sand's surface. One set of pulses is longitudinal while the other set is transverse.

Explain the types of waves based on the direction of oscillations of the particles of the medium.

Transverse and longitudinal waves can propagate in solids,whereas only longitudinal waves can propagate in air. Explain this statement.

Sound waves exhibit more diffraction than light waves because:

Water waves are
