The answer to the question is sound
At the boundary between air and glass, we can see mainly refraction ...
the path of the light bends as it crosses the boundary, and proceeds
from there in a different direction.
If we're very careful and make sensitive measurements, then we can also
detect transmission, some reflection, and a tiny bit of dispersion at the boundary.
I would say B , not sure if its correct
Answer:
Not Equal.
Explanation:
As the direction from New York to Miami (due South) is different from the direction from New York to Chicago (due West), the 2 velocities are not equal despite having the same magnitude. If both cars are to travel to the same destination at same speed, their velocities would be equal.
