The characteristics that remains unchanged when a wave changes its mediums.
Answer to Problem 31SSC
Characteristics like frequency, amplitude, wavelength, velocity and direction may change when entered into different medium.
Explanation of Solution
When a wave changes mediums, velocity and wavelength change according to the medium. These two characteristics depend on the properties of the medium itself.
Frequency of the wave remains same as it not dependent on the medium in which the wave is travelling.
Conclusion:
Velocity and wavelength changes whereas frequency remains unchanged according the medium.

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…arrow_forward
