It is called the Doppler effect
Water flows over the edge of a waterfall due to gravity, forming a cascading effect as it falls towards the bottom. The water gains speed and momentum as it falls, creating a splashing effect upon impact with the bottom.
A falling snowflake or raindrop does not accelerate as it approaches the ground because their mass doesn't change. The form is not affected throughout the fall so it is already approaching the ground at terminal velocity. Hope this helps.
As an object falls towards the Earth's surface, its velocity increases due to the acceleration caused by gravity. Near the surface, the object will reach a terminal velocity where the force of air resistance equals the force of gravity, causing the object to fall at a constant speed.
Everything falls at the same speed. the only variable is drag. For instance a feather & a bowling ball would fall at the same speed in a vacuum, but not through the air.
Frequency 47993 Hz is not known to have any specific effect on people as it falls within the ultrasonic range, beyond the audible range of human hearing. There is no scientific evidence to suggest that this frequency has any physiological or psychological impact on individuals.
