Question

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as:
A. Transverse wave
B. Propagated waves
C. Longitudinal waves
D. Stationary waves

Answer 1

Hint: Wave is a vibration or disturbance in space. This vibration causes a propagated pattern of wave. According to how the particles are moving, waves can be classified into transverse and longitudinal waves.

Complete step-by-step answer:
If the particles are moving perpendicular to the motion of the wave, then the wave is known as transverse waves. The following diagram represents the motion of waves and particles motion.
Hence the correct option is A.

Additional information:
Transverse and longitudinal waves are under the category of mechanical waves. They need a medium for the propagation. Water waves, sound waves and seismic waves are the examples for this.
Transverse waves: It occurs when the individual particles or segments of a medium vibrate from side to side perpendicular to the direction in which the direction of propagation of wave.
Longitudinal waves: Unlike transverse waves, the longitudinal waves occur when the individual particles of a medium vibrate back and forth in the same direction of waves propagation. They are most common in the springs. It will generate due to the pushing or pulling of the spring.
Stationary waves: Stationary waves also known as standing waves. These waves are a combination of two waves of the same frequency. So, the interference will occur. Their wave velocity is zero. These waves will be in the same phase. It doesn’t carry energy with the waves.

Note: All other waves have their own characteristic properties. Longitudinal waves are the waves in which the particles are moving with the same direction of the propagation of waves. Standing wave is a superposition of waves of similar frequency. Propagated waves are implying the way in which the wave travels.
