Pls help!! Question:
Write an evidence based explanation how differing the index of refraction, n, values affects how a light ray bends when transitioning from one medium to another. Your explanation should include the light ray traveling from 1) high index of refraction to low index of refraction and 2) low index of refraction to high index of refraction.

where is the photo and the answer choices?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
