Answer:
b) normal
Explanation:
The angle of refraction (transmission) Θt is the angle between the refracted ray and the normal N'. 2. When a light ray hits a surface normally, the angle between the incident ray and the normal is 0, so Θi = 0. Since the angle of reflection equals the angle of incidence, Θr= 0.
(1,500 meters) x (1 sec / 330 meters) = (4 and 18/33) seconds
(4.55 sec, rounded)
To find the x component use the following formula, where Ф = theta = the angle 'a' makes with the x axis.
I believe the best answer is law, as scientific laws are accepted to be true under the proper conditions.
