1. During daytime when sound propagates in air, temperature changes with altitude sound bends towards (hotter, cooler) region.
2. (Refraction, Reflection) is due to the different refractive indices of air because of the difference of temperature.
More3. During the day the sound travels faster (near, far) the ground.
@4. Sound wave refract (upwards, downwards) during daytime.
5. The sound farther from the ground travels (faster, slower) at night causing the sound wave to refract back towards the
earth.
