Two spaceships are observed from Earth to be approaching each other along a straight line. Ship A moves at 0.40c relative to the Earth observer, while ship B moves at 0.50c relative to the same observer. What speed does the captain of ship A report for the speed of ship B?

(i) A sound source emitting sound at a single frequency moves with constant speed along x-axis as shown in figure (a). A and B are two stationary observers. The three plots shown in figure (b) indicate the pressure function P(x) of the sound wave as recorded by the observer A, by B, and by another observer C who is at rest in the frame of the source. Which plot (marked as 1, 2 and 3) correspond to which observer? (ii) Each of the two figures is rough illustration of the resulting waveform (y versus t ) due to overlapping of two waves. The four component waves have frequencies of 300 Hz, 200 Hz, 204 Hz and an unknown frequency f=300+Deltaf . Is Deltaf higher than or less than 4 Hz ?
