waves, wave speed/type

A fisherman notices that wave crests pass the bow of his anchored boat every 4.0seconds. He measures the distance between two crests to be 9.0 m. How fast are the waves traveling? **please explain this in the simplest, least confusing way....thank you so much :)

waves: type, speed

A rope of mass 0.65 kg is stretches between two supports 30m apart. If the tension in the rope is 120 N, how long will it take a pulse to travel from one support to the other? **please explain this in a simple, unconfusing way...thanks

wave motion

S and P waves from an earthquake travel at different speeds and this difference helps in the determination of the earthquake "epicenter", (where the disturbance took place). (a)assuming typical speeds of 9.0km/s and 5.5 km/s for P and S waves, respectively, how far away did the earthquake occur if a particular seismic station d ...continues

wave parameters and equation

a transverse traveling wave on a cord is represented by D = 0.48 sin (5.6x +84t) where D and x are in meters and t in seconds. For this wave determine (a) the wavelength (b) the frequency (c) velocity (magnitude and direction) (d) amplitude and (e) maximum and minimum speeds of particles of the cord.

wave parameters and equation

A violin string vibrates at 294 Hz when unfingered. At what frequency will it vibrate if it is fingered one-fourth of the way down from the end?

linear superposition, interference

A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake. She hears the echo 1.5 s after shouting. Estimate the length of the lake.

linear superposition, interference

(a) calculate the wavelengths in air at 20°C for sounds in the maximum range of human hearing, 20 Hz to 20,000 Hz. (b) what is the wavelength of a 10-MHz ultrasonic wave?
