Question
In the diagram, the two block dots represent point wave sources and the crests of the radiating wave fronts are shown.
a. ______List the lettered point(s) at which constructive interference occurs.
b. ______List the lettered point(s) at which destructive interference occurs.
c.______Use a ruler to determine the wavelength of the waves produced by the sources assuming that this is an actual size diagram.
d. _____Suppose the source produce 5 waves each second. Use the wavelength from part C to determine the waves speed.
e.______ If the wave frequency was cut in half, by what factor would the wavespeed change?
f.______If the wave frequency was cut in half, by what factor would the wavelength change?
g. _____If the separation between S1 and S2 was increased with the spacing between the lines of constructive interference increase or decrease or decrease or stay the same?
h.______If the wavelength produced by S1 and S2 increased, would the spacing in between the lines and constructive interference increase or decrease or stay the same?
Explanation / Answer
a.)where the two waves intersect are constructive intrference
at Point A and D wave intersect so these are constructive interference.
b.) POint B and C are destructive interference
c.)wavelength is the radial distance between two consecutive wave. it is around 2cm
d.)v = frequency* wavelength
V = (1/5)*0.02
V = 4*10^-3 m/s
e.)it will remain constant at the fequency double the wavlength gets half
f.)wavelength become double
g.)same
h.)increases
