Demonstrate how pitch, timbre and volume are related to wave
shape, amplitude and frequency (not in that order) by writing a
paragraph about these relations including examples from real
life
Given two wave that has the same amplitude, frequency and
direction that they are traveling in, BUT they have a phase that is
a difference of 2Pi. When one adds both waves up we get:
a) Nothing
b) A wave with twice the wavelength of the original
c) A wave with twice the amplitude of the original
d) A wave with twice the frequency of the original
e) None of the above
A transverse traveling wave on a taut wire has an amplitude of0.200
mm and a frequency of 530 Hz. Ittravels with a speed of 196 m/s.
(a) If the wave equation is written in the
formy = A sin(kx - ωt), whatare
the parameters A, k, andω?
1 m
2 rad/m
3 rad/s
(b) The mass per unit length of this wire is 3.50 g/m. Find the
tension in the wire.

A sound wave in air at 20 Celsius has a frequency of 151 Hz and a displacement amplitude of 5.40×10-3 mm.Part AFor this sound wave calculate the pressure amplitude (in Pa).Use 1.42×105 Pa for the adiabatic bulk modulus.Pmax= 2.11 PaPart BFind the intensity of the waveUse 1.20 kg/m^3 for the density of air.I=?
1.A wave of amplitude 0.36 m interferes with a second wave of
amplitude 0.21 m traveling in the same direction.
(a) What is the largest resultant amplitude that can occur, and
under what conditions will this maximum arise?
?m
The two waves interfere destructively. The two waves interfere
constructively.
(b) What is the smallest resultant amplitude that can occur, and
under what conditions will this minimum arise?
?m
The two waves interfere destructively.The two waves interfere
constructively.
2.On a hot...
sinusoidal wave of angular frequency 1205 rad/s and amplitude
3.20 mm is sent along a cord with linear density 2.10 g/m and
tension 1233 N. (a) What is the average rate at
which energy is transported by the wave to the opposite end of the
cord? (b) If, simultaneously, an identical wave
travels along an adjacent, identical cord, what is the total
average rate at which energy is transported to the opposite ends of
the two cords by the waves?...
