Answer:
0.139 rad
Explanation:
We use Snell's law , where if is the <em>refractive index</em> of the medium containing the <em>incident ray</em>, would be the <em>incident angle</em>, and if is the <em>refractive index</em> of the medium containing the <em>refracted ray</em>, would be the <em>refraction angle</em>, which we want, so we do:
And finally:
We then insert our values:
Answer:
so eaasy
Explanation:
bro this is so easyyyyyyy
100 meters in 9.92 seconds,
=distance/time
