A standing wave pattern with 5 nodes is created in a string of length 1.2 m by using waves of frequency 101.0 Hz. What is the speed of the waves in m/s? Answer:

Two waves, of the same wavelength are travelling in opposite directions.  One wave has an amplitude of 10 cm, while the other wave has an amplitude of 5 cm.  What is the magnitude of the amplitude of the resulting wave when the waves are constructively interfering?   Question 5 options:   5 cm   20 cm   15 cm   10 cm

A string of length L is under tension, and the speed of a wave in the string is 58 m/s.  What will be the speed of a wave in the string, in m/s, if the length is doubled but with no change in the mass or tension?

The function y(x, t) = A cos(kx - wt) describes a traveling wave on a taut string with the x-axis parallel to the string. If the wavelength of the wave λ = 0.8 m and w = 17.1л/s, what is the speed of the traveling wave? Express your answer in m/s, to at least one digit after the decimal point.

A capillary wave is a wave traveling across the surface of a fluid that is driven by the surface tension within the fluid.  The speed v of a capillary wave depends on the density of the fluid ?ρ , the wavelength of the wave ?λ, and the surface tension ?σ .  The SI units of surface tension are J/m2.  The capillary wave speed can be written as  ?=???????v=kσaρbλc  , where k is some unitless constant.  What must be the value of c?

A transverse traveling wave on a taut wire has an amplitude of 0.200 mm and a frequency of 530 Hz. It travels with a speed of 196 m/s. (a) If the wave equation is written in the form y = A sin(kx - ot), what are the parameters A, k, and w? m rad/m rad/s (b) The mass per unit length of this wire is 4.30 g/m. Find the tension in the wire.

Two progressive waves y (x, t) = A sin( 4 x – ot) and y2(x, t) = A sin(4x - - - ) travel in the same direction. Calculate the speed of the wave produced as a result of interference of these two waves. Take A = 5 cm, 1 = 4 m and w = 31.4 Hz. Provide your answer in Sl units.

Two progressive waves yj = A sin( 4 x - ot) and y2 = A sin( 2" x – ot – 5) travel in the same direction. Calculate the velocity of the wave produced as a result of interference of these two waves. Take A = 5 cm, 1 =8.7 m and w =12.7 rad/s (radian per second). Give your answer in Sl units.

Transverse waves on a string have a velocity of 15 m/s, amplitude of 0.10m and a wavelength of 25 cm. The waves travel in the +x direction and at t=0 the x=0 end of the string is at a maximum upward displacement. Find the wave number of the wave (m):

In an experiment, students were testing their hearing range and found that it averaged about24.5 Hz to 1.82 x 104 Hz. What are the wavelengths of sound waves producing these frequencies in air where the speed of sound is 343 m/s?
