An underwater scuba diver scuba diver looks up to the waters surface she sees a buoy floating on the surface and notes it’s location. she then realizes that the buoy could actually be in a different location because she is looking at it from underwater. what is the wave property that best explains this phenomenon? a) absorption b) diffraction c) reflection d) refraction

Option (D)

Explanation:

The given question is based on the refraction of light.

Refraction of light is usually defined as the process by which a light wave gets bend or curved or deviated due while changing its medium from a rarer to a denser medium. For example, a ray of light gets bend when it travels from air (rarer medium) to a liquid medium (denser medium).

This means the velocity of the light or wave decreases when it changes its medium from rarer to a denser medium.

Thus, the wave property that describes the the given phenomenon is the refraction of light.

Therefore, the correct answer is option (D).

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .

the answer is d (apex) good luck : ))
