Which describe reflection? check all that apply.

correct answers

light bounces off a boundary.
light passes through a boundary.
light travels to another medium.
light remains in the same medium.
light direction is determined using snell’s law.
light direction is determined using the law of reflection.

Explanation:

In physics, reflection is studied using light rays. Specifically, it's the process of bouncing off an object surface, that is, the light hits a surface and "move back".

This subject is studied in geomtric optics, because we use the geometry tools to understand, analyse and predict the behaviour of a light beam when hits an object.

Reflection is studied applying the Law of Reflection which statest that the angle of incidence is congruent with the angle of reflection regarding a normal axis. The image attached shows this law.

Therefore, the correct answer are the first and last choice, because as we said before, reflection is the light action of bouncing off a boundary or a object surface, if light doesn't bounce off and instead goes through, that's called refraction. Also, we saw that the law of reflection basically defines light reflections phenomena.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
