An underwater scuba diver looks up toward the water's surface. she sees a buoy floating on the surface and notes its location. she then realizes that the buoy may actually be in a different location because she is looking at it from underwater. what is the wave property that best explains this phenomenon?

Refraction

Explanation:

As here the scuba driver is looking from an optically denser medium to an optically rarer medium the boy may appear nearer to the diver in position than is actually in the air.

Snell's law gives the relation between the angle of incidence and the angle of refraction as:

where

n = refractive index

i = angle of incidence

r = angle of refraction

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
