The direction of a light ray changes as it passes from one medium to another. The phenomenon is called?

Refraction

Explanation: In physics, refraction is the change in route of a wave passing from one medium to any other or from a gradual alternate in the medium. Refraction of light is the most typically located phenomenon, however other waves such as sound waves and water waves additionally journey refraction.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

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.
