Explanation:
For air, n1 = 1.00003; for water, n2 = 1.3330
Given: θ2 = 30 degrees, then
θ1 = arcsin [(n2/n1) sin θ2]
= arcsin [(1.3330/1.0003) sin (40)]
= 58.93 degrees
Note that since, in this example, light is traveling from a medium of higher density (water; n2 = 1.3330) to a medium of lower density (air; n1 = 1.0003), then n2 > n1, and the angle of refraction (θ1) is larger than the angle of incidence (θ2), thus the light bends away from the normal (in this example, the vertical) as it leaves the water and enters the air.
It is the only one that has both a partially molten metallic core and reasonably rapid rotation.
<h3><u>Answer;</u></h3>
c) created when tectonic plates converge
<h3><u>Explanation;</u></h3>
- According to the plate tectonics theory, earthquakes, volcanoes and mountain building process occur due to the interaction of the rigid plates on the earth's crust.
- <u>Mountains are as a result of volcanoes which are created by the movement of plate tectonics, which erupt and form mountains.</u> Formation of these mountains is as a result of compression of sediments caused by the collision of two convergent plate boundaries.
- It's along the convergent plate boundaries that interactions occur which creates volcanic activities and mountain building.
