Answer:
<h2>A stationary object with no outside force will not move. With no outside forces, a moving object will not stop. An astronaut who has their screwdriver knocked into space will see the screwdriver continue on at the same speed and direction forever. There are no forces acting on the screwdriver from friction </h2>
They actually bounce off a charged layer of atmosphere to reach stations beyond the curvature of the Earth. The correct option among all the options that are given in the question is the last option or option "d". The radio waves bounce off the ions present in the ionosphere of earths atmosphere and reach stations beyond the curvature of Earth.
If a ray passing from one medium to other medium then it will refract either away from normal or towards the normal
This all we can find out using snell's law
now if we wish to find the angle inside other medium then we will have
now if light ray bend towards the normal then
so second medium must be optical denser
otherwise if light ray is bending away from the normal then
so second medium is rarer than first medium
so for the given condition of the question correct answer will be
<em>refraction with medium 1 denser than medium 2</em>
