Which of the following occurs as a light wave bends when it passes from one medium to another
1 answer:
<h2>Answer: c. Refraction</h2>
Refraction is a phenomenon in which a light wave bends or changes its direction when passing through a medium with a <u>refractive index</u> different from the other medium.
Being the <u>refractive index</u> is a number that describes how fast light propagates through a medium or material, and is defined as the relation between the speed of light in vacuum (
) and the speed of light
in the second medium:
It is important to note that in this process, the wavelength may be modified because it depends on the medium, however, the refracted ray of light does not change its frequency.

Answer:
3.486 km
Explanation:
Suppose Joe and Max's directions are perfectly perpendicular (east vs north). We can calculate their distance at the destinations using Pythagorean theorem:
where J = 0.5 km and M= 3.45 km are the distances between Joe and Max to their original parting point, respectively. s is the distance between them.
