Question

A ray of light travelling in medium 1 strikes and travels into another transparent medium, medium 2. If the speed of light is greater in medium 1, the ray will

Answer 1

When a ray of light enters a medium with a higher refractive index, it bends towards the normal, resulting in the ray moving closer to the perpendicular. This is illustrated in Figure 1.13(a).

Step-by-step explanation:

A ray of light traveling from one medium to another will change its path as a result of refraction. When light enters a medium with a higher refractive index, it bends towards the normal, which is a line perpendicular to the surface of the two media. Therefore, if the speed of light is greater in medium 1 and it strikes and travels into medium 2, the ray of light will move closer to the perpendicular, as shown in Figure 1.13(a).

Answer 2

The question is incomplete, the complete question is;

A ray of light travelling in medium 1 strikes and travels into another transparent medium, medium 2. If the speed of light is greater in medium 1, the ray will ............ *

refract away from the normal.

undergo total internal reflection.

refract towards the normal.

have an angle of incidence smaller than the angle of refraction.​

Answer:

refract towards the normal.

Step-by-step explanation:

Refraction refers to the bending of light waves or change in the direction of light waves as a result of change in the speed of light at the boundary between two media.

Whether the rays bend towards or away from the normal depends on the density of the both media. When light travels from medium 1 to medium 2 and medium 1 is less dense than medium 2(shown by a greater speed of light in medium 1 than medium 2) then the ray of light refract towards the normal and vice versa.
