• WAVE MOTION: Waves play an important role in our daily life. It is because waves are carrier of energy and information over large distances. Waves require some oscillating or vibrating source. Here we demonstrate the production and propagation of different waves with the help of vibratory motion of objects.
• Important class 10 physics chapter 1 important questions for all students of Punjab  Textbook Board.
• From the above simple activities, we can define wave as:
• "A wave is a disturbance in the medium which causes the particles of the medium to undergo vibratory motion about their mean position in equal intervals of time".
• There are two categories of waves:
• 1. Mechanical waves 2. Electromagnetic waves
• Mechanical Waves: Waves which require any medium for their propagation are called mechanical waves.
• Important important question of physics class 10 chapter 1 for all students of Punjab  Textbook Board.
• Examples of mechanical waves are water waves, sound waves and waves produced on the strings and springs.
• Electromagnetic Waves: Waves which do not require any medium for their propagation are called electromagnetic waves.
• Important physics class 10 chapter 1 important questions for all students of Punjab  Textbook Board.
• Radiowaves, television waves, X-rays, heat and light waves are some examples of electromagnetic waves.
• TYPES OF MECHANICAL WAVES: Depending upon the direction of displacement of medium with respect to the direction of the propagation of wave itself, mechanical waves may be classified as longitudinal or transverse.
• Important physics important questions class 10 chapter 1 for all students of Punjab  Textbook Board.
• Longitudinal waves can be produced on a spring (slinky) placed on a smooth floor or a long bench. Fix one end of the slinky with a rigid support and hold the other end into your hand. Now give it a regular push and pull quickly in the direction of its length.
• A series of disturbances in the form of waves will start moving along the length of the slinky. Such a wave consists of regions called compressions, where the loops of the spring are close together, alternating with regions called rarefactions (expansions), where the loops are spaced apart.
• Important class 10th physics chapter 1 important notes for all students of Punjab  Textbook Board.
• "In longitudinal waves the particles of the medium move back and forth along the direction of propagation of wave".
• Therefore, transverse waves can be defined as:
• "In case of transverse waves, the vibratory motion of particles of the medium is perpendicular to the direction of propagation of waves".
• Waves on the surface of water and light waves are examples of transverse waves.
