In this chapter, we will see how trigonometry is used for finding the heights and distances of various objects, without actually measuring them. 9.2 Heights and Distances
Waves Notes PDF. The Class 11 Physics notes is a written explanation for every passage or concepts included in the chapter Waves. These Waves notes are available in the Portable Document Format. The PDF of the Class 11 Physics Notes can be easily downloaded without any difficulty.
Waves Summary Notes. Waves transfer energy The higher the amplitude the greater the energy of the wave. f=no. of waves produced per second T= time for 1 wave to pass a point. Transverse Wave: The particles of the medium transmitting the wave travel at right angles to the direction of energy travel. e.g. E.M. waves.
In summary, \(y(x, t)=A \sin (k x-\omega t+\phi)\) models a wave moving in the positive x-direction and \(y(x, t)=A \sin (k x+\omega t+\phi)\) models a wave moving in the negative x-direction. Equation \ref{16.4} is known as a simple harmonic wave function. A wave function is any function such that \(f(x, t)=f(x-v t)\).
A wave is a disturbance that moves from the point of origin with a wave velocity v. A wave has a wavelength \(\lambda\), which is the distance between adjacent identical parts of the wave. Wave velocity and wavelength are related to the wave’s frequency and period by v = \(\frac{\lambda}{T}\) = \(\lambda\)f.
Waves: This chapter explores the nature of waves, including types of waves (mechanical and electromagnetic), wave properties, and wave phenomena such as interference and diffraction. Key Features of the Textbook
Model a wave, moving with a constant wave velocity, with a mathematical expression; Calculate the velocity and acceleration of the medium; Show how the velocity of the medium differs from the wave velocity (propagation velocity)
