Question

If we throw a stone in a pond in a pond of standing water, the waves produced are:
A. Transverse in nature
B. Longitudinal in nature
C. A combination of transverse and longitudinal in nature
D. Of some other type

Answer 1

Hint: Here we have to examine each of the options one by one to get the answer. In this question,we are going to apply the concept of waves and its various. There are two types of waves produced- longitudinal and transverse.

Complete answer:
Transverse wave: Transverse wave, a motion in which all points on a wave oscillate in the direction of the wave 's advance along paths at right angles. Examples of transverse waves are surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves.

The particle displacement in a transverse wave is perpendicular to the direction of wave propagation. The particles do not move along with the wave; as the wave moves past, they merely oscillate up and down around their different equilibrium positions.

Longitudinal wave: A longitudinal wave, a wave composed of a periodic disturbance or acceleration in the same direction as the wave 's advance. Sound travelling through air often compressed and rarefied gas as it vibrates back and forth in the direction of the sound wave 's movement.

Longitudinal waves are waves in which the movement of the medium's individual particles is in a direction that is parallel to the energy transfer direction. In such a case, in directions parallel to the direction in which the energy is transported, each actual coil of the medium is set into vibrational motion.

Combination of longitudinal and transverse waves: An example of waves containing a combination of both longitudinal and transverse motions is water waves. The particles move in clockwise loops while a wave circulates around the waver. If the depth increases in the bath, the radius of the circles decreases.

Hence, we can see that if we throw a stone in a pond in a pond of standing water, the waves produced are a combination of longitudinal and transverse waves.

Thus, option C is correct.

Note:As water waves exhibit properties of both transverse and longitudinal nature. So, they are a combination of transverse and longitudinal waves. Moreover,a wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.
