how much light bends depends on what?

How much light bends depends on the speed of the light and the nature of the medium through which it travels

Explanation:

Refraction is defined as change in the direction of light rays as it moves from one medium to another. As ray of light travels from one medium to another, the ray of light bends either towards the normal or away from the normal. This change in the direction of light is due to the speed of the light and the nature of the medium through which the light travels. If the light travels from a less dense medium to a denser medium, the light rays refracts and bends towards the normal but If the light travels from a denser medium to a less dense medium, the light rays refracts and bends away from the normal.

explanation:

2b2t

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
