As light travels through air and then travels through water, which picture best shows what happens to the ray of light?(1 point)

Question

A. A glass of water with two arrows, one arrow is pointing inside of the cup and the other and arrow is inside of the cup but pointing outside of the cup and a majority of the arrow is inside of the water keep in mind that the first arrow is touching the bottom of the second one so together they kind've form a v shape.
B. A glass of water with two arrows, one arrow is pointing inside of the cup and the other arrow is fully inside of the cup pointing downwards at a diagonal on the right, keep in mind that the first arrow is touching where the second arrow begins and the first arrow is also pointing downwards at a diagonal but to the left.
C. A glass of water with two arrows, one arrow is pointing downward inside of the cup at a diagonal on the left and the other arrow is pointing in the same direction but the tip of the arrow is slightly outside of the cup itself
D. A glass of water with two arrows, one arrow is pointing downward inside of the cup at a diagonal on the left and the other arrow is pointing in the same direction but it is more steep and points more in the corner of the cup ( the pictures shown are 2d )

Answer 1

When light travels from air into water, it undergoes refraction, which means it changes direction due to the difference in density between the two mediums. The light ray will slow down and bend towards the normal line (the perpendicular line to the surface at the point of incidence).

Looking at the options, the description that fits the behavior of light as it enters water from air is best represented by option A. The first arrow (representing the light traveling in air) is pointing toward the water's surface, and the second arrow (representing the light in water) is pointing downwards inside the cup, forming a "V" shape, showing the change in direction of the light ray as it enters the water.

So, the correct choice is A.
