As light moves from one material into the next, which of the following affects how much the light waves will refract, or bend? angle at which the ray strikes the medium color of the material density of the material temperature of the light wave

Density of the material

Explanation:

When light travels from one medium to another, it's direction changes. This is why a spoon will appear to a user as bent when in water or a straw bends in a bottle of soda.

Light refracts when it changes from one medium to another due to the density difference.

Refraction of light causes the rays of emergent light to be tilted or bent in a particular direction. Refraction plays an important role in the formation of rainbows.

b) mutualism

hope this : )

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
