o say, all the reflected rays will diverge froma point D\ as far behind the deviating surface as thepoint D of disturbance is in front of it. The reflectedpulse will, therefore, be spherical. From the point D as a centreand radius D K, equal to thatof the spherical pulse at anyinstant, describe the… … ELEMENTS OF ACOUSTICS. 87 describe the arc 0 K 0; this will represent a section, construction ofby the same plane, of the reflected pulse. Draw any ^rnact^an^incident ray as D C; through the point H, given by the reflected pulses.value of f in Equation (32), and the point (7, draw H C,which being…
