6. The speed v of waves on a string is given by v (F/)12, where F is the tension and H m/L is the mass per unit length of the string. If you double the wavelength λ of a wave on a string, what happens to the wave speed v and the wave frequency f?
Question 4 to 11 plz Dr? Standing Waves on a String Physics Topics If necessary, review the following topics and relevant textbook sections from Serway / Jewett "Physics for Scientists and Engineers", 9th Ed. • Mathematics of Traveling Waves (Serway 17.2) • Speed of Waves on a String (Serway 17.3) • Superposition of Waves (Serway 18.1) • Standing Waves on a string (Serway 18.2, 18.3) Introduction Imagine two sinusoidal traveling waves with equal amplitudes and frequencies moving in opposite directions....
segments over the length L of the string, where the length of each vibrating segment equals one-half wavelength. Use this fact to show that the fr of the allowed standing waves on this string are given by fn-nfi, where n 1,2,3, 4,5,... and fi is the fundamental frequency. In other words, derive an expression relating the nth harmonic to the fundamental frequency. Yo may use the fact that the wave velocity is the same for all modes. 1. For a...
If we increase the Tension (T) of a wave, the velocity of the wave increases (via v=sqrt(Tension/u)). Now using v=f*, what then happens to the frequency and wavelength? Does the frequency increase and the wavelength stay constant (or decrease)?
QUESTIONS 1. Calculate the velocity of the wave when the string is vibrating in three segments. 2. Suppose the pulley absorbs a significant fraction of the energy in the wave so that the ampli- tude of the reflected wave is not equal to the amplitude of the wave set up by the vibrator How will the standing waves differ from those established under conditions of perfect reflec- tion? Hint: Remember what happens to the nodes when you add two waves...
a) Consider interference of two wavefronts with equal amplitudes but slightly different wavelengths lambda = 2 pi/k: Psi(x, t) = A cos(omega_k t - kx) + A cos (omega_(k + delta k)t - (k + delta k)x) Derive and explain equations for phase and group velocity using this example b) What are phase and group velocity of light? c) Surface waves, e.g. on water, obey a more complicated dispersion, omega_k = C_k k, with c_k = B Squareroot k What...
What is the answer for (b) and (c) ?? Two waves are generated on a string of length 3.2 m to produce a three-loop standing wave with an amplitude of 7.4 cm. The wave speed is 111 m/s. Let the equation for one of the waves be of the form y(x, t) = y_m sin (kx + omega t). In the equation for the other wave, what are y_m, k, omega, and the sign in front of omega?
