A refraction pattern in which rays are bent concave upward can be caused by
A)increased moisture.
B)strong winds.
C)a steady, steep drop in temperature with height.
D)low clouds.

Question

Quizplus · Accepted Answer

A steady, steep drop in temperature with height causes a temperature inversion, which can lead to a phenomenon known as a superior mirage, in which the image of an object appears to be lifted or stretched upward. This is due to the bending of light rays towards the colder and denser air near the ground, creating a concave upward refraction pattern. Increased moisture (A), strong winds (B), and low clouds (D) can affect visibility and cause other types of refraction patterns, but do not necessarily result in concave upward bending of light rays.
