The word you are looking for is <em><u>refraction. </u></em> Reflection is when 100% of the light is bounced back, refraction, however if when light <em>bends</em>, or, changes wavelengths.
Answer:
d = 493.72 m
Explanation:
Given that,
Initial velocity of the train, u = 80 km/h = 22.22 m/s
Acceleration of the train, a = -0.5 m/s² (negative as it slows down)
Finally brakes are applied, v = 0
We need to find the distance the train travels. Let the distance be d. Using third equation of kinematics to find it.
So, the required distance is equal to 493.72 m.
<em>g</em> is the vector (6, 3), since it starts at the origin and terminates at the point (6, 3).
We can write this as a sum of the scaled unit vectors (1, 0) and (0, 1),
(6, 3) = (6, 0) + (0, 3)
where (6, 0) is the <em>x</em>-component of <em>g</em> and (0, 3) is the <em>y</em>-component. The lengths of these component vectors are clearly 6 and 3, respectively.
(a) refraction
Refraction is the bending of light that causes something in water looks as though it is bend or crooked
