Explanation Given info : The speed of the P wave ( v 1 ) at the first medium is ( 8 .0 km/s ( 8 .0 × 10 3 m/s ) ) with incident angle ( θ i ) of 44 ° . The refraction angle ( θ r ) of 33 ° . Formula used : According to the law of refraction: sin ( θ r ) sin ( θ i ) = v 2 v 1 (1) Where, θ r is the angle of refraction. θ i is the incident angle. v 2 is the speed of P wave in the second medium. v 1 is the speed of P wave in the first medium

Equation of Waves

Wave is an oscillation or disturbance traveling in a medium. It performs the transportation of energy but does not carry any matter. This motion of waves will transport fuel in a medium without permanent transfer of mass (particle).

13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…
