Answer:
1.09 km, 3 km
Explanation:
displacement, d = 3.20 km at 20° North of east
A vector quantity has two components one along the x axis and the other is along Y axis. the component along X axis is called the horizontal component and it is due east.
The component along y axis is called vertical component and it is due North.
Displacement due North, dy = 3.20 Sin 20° = 1.09 km
Displacement due east, dx = 3.20 Cos 20° = 3 km
Thank you kind person
*hands you a whole gallon of ketchup :)))
For the total internal reflection of a substance, we can express the relationship between the critical angle,
, and the indices of refraction as
(1) <span>
</span>
where
and
are the indices of refraction. And under polarization, we can express Snell's Law as
Rearranging this we have
(2)Substituting equations (1) into (2), we have
Substituting the value of the critical angle, we have
Answer: 33.79°
