Figure shows wave fronts coming 10 form a source at equal interval of 3 milli second Frequency of wave emitted by source is 300 Hz XX is line along common diameter of wave fronts passing through A Distance between two consecutive wave fronts along line XX is 0 9 m and 1 3 m in the right and left of point A respectively At some instant source is at point A Detector is placed at point Q AQ makes an angle 60 with line XX If frequency of wave received by detector is f Hz then f 110 in Hz is oqual to 3 1 3 m 0 9 m X
