Question
Distinguish between longitudinal and transverse waves.
✓
Answer
Longitudinal wave: A wave in which the particles of the medium vibrate back and forth in the ‘same direction’, in which the wave is moving, is called a longitudinal wave. These waves can be produced in all the three media: solids, liquids and gases. Transverse wave: A wave in which the particles of the medium vibrate up and down, ‘at right angles’ to the direction in which the wave is moving, is called a transverse wave. It can be produced in solids and liquids but not in gases.

An automobile engine propels a $1000kg$ car $(A)$ along a levelled road at a speed of $36km h^{-1}$. Find the power if the opposing frictional force is $100N$. Now, suppose after travelling a distance of $200m$, this car collides with another stationary car $(B)$ of same mass and comes to rest. Let its engine also stop at the same time. Now car $(B)$ starts moving on the same level road without getting its engine started. Find the speed of the car $(B)$ just after the collision.
