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.​

refract towards the normal.

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.

the glands which are associated with each description is given below:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
