Which diagram best shows the perceived sound wave heard by a woman after a police car has passed her? An illustration of a person listening to the siren of a passing police car. There are circles spreading out from the siren with the wavelength close together in the front and farther apart in the back.
An illustration of a person listening to the siren of a passing police car. There are circles spreading out from the siren with the wavelength longer closer to the siren and closer together the farther from the siren on both sides.
An illustration of a person listening to the siren of a passing police car. There are circles spreading out from the siren that are concentric and evenly spaced.
An illustration of a person listening to the siren of a passing police car. There are circles spreading out from the siren with the wavelength changing in all directions.

Space-time metric ds2= -dt2+at2dx2+bt2dy2+ct2dz2 (a)how does the area of a rectangle with vertices at ( x=0, y=0, z=0 ), (1,0,0 ), ( 0,1,0 ) and (1,1,0 ) changes with time? (b) if a photon moving in the x direction starts from the origin at t=1, when does it reach x=l? (ds=0 for the trajectory of a photon.) (c) the proper time for a particle is defined by cd=ds. what is the proper time for a particle to move along the trajectory ( x(t)=t, y(t)=0, z(t)=0 ) from t=0 to 1 ? what is the condition on the parameter a so that the velocity of the particle never exceeds the speed of light ?
