Which is an example of refraction A. a flashlight beam hitting a mirror
B. a shout crossing a crowed room
C. a sunbeam striking a window
D. a water wave bending around a rock

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
