Important Topics for Resnick Halliday & Walker Fundamentals of Physics Volume 1 Solutions Chapter 16: Waves – I

Waves: A wave is known as the disturbance of one or more fields such that the value of the field oscillates in a repeated manner about a stable equilibrium value.

Types of Waves: 

  • Mechanical Waves – We encounter mechanical waves almost constantly. Some examples are water waves, sound waves, seismic waves. In the chapter, you will study the features of mechanical waves.
  • Electromagnetic Waves – People are not much familiar with these types of waves but the common examples include visible and ultraviolet light, television and radio waves and radar waves, etc. in the chapter you will know how these types of waves travel.
  • Matter WavesThese waves are used in common modern technology but they are unfamiliar to you. In the chapter, you will know how the waves are associated with protons, electrons, and other particles. 
  • Transverse WavesWhen the displacement of a string element is perpendicular to the direction of travel of waves. This is known as transverse motion and the waves associated are transverse waves.
  • Longitudinal WavesWhen the motion of the air element is parallel to the direction of wave travel, then the motion set to be longitudinal. The wave is known as a longitudinal wave. 

In the chapter, you will know how transverse waves and longitudinal waves are known as travelling waves. Some other important topics that you would come across in Resnick Halliday & Walker Fundamentals of Physics Waves Chapter are given below:

Wavelength: Wavelength is the distance between the repetition of the shape of the wave. 

Amplitude: The amplitude of a wave is the measurement of maximum displacement of elements from their equilibrium positions as the wave passes to them. You will know why amplitude is always a positive quantity. 

Periods: Period of oscillation T of a wave is the time that any string element takes to move through one full oscillation.

Power: The average power or the average rate at which energy is transmitted by sinusoidal waves on a stretched string is given by an equation:

Superposition of Waves: When two or more waves mainly traverse the same medium, the displacement of any particle in the medium is the sum of the displacements that individual waves will give it. 

Interference of Waves: Two sinusoidal waves when staying on the same string experience interference, adding or cancelling takes place according to the principle of superposition of waves. In the chapter, you will know how they differ in their phase constant values.
