The answer would be: Winter
The Southern hemisphere is tilted to the left, few degrees away from the sun. This condition will result in more(to maximum) exposure to the sunlight, lead to the summer. The condition is the opposite of the northern hemisphere where it has less area that exposed to sunlight, lead to winter.

Frequency is often measured by counting the number of crests or troughs that pass by a given point in one second”
The second one would be a medium “Mechanical waves require a medium in order to transport their energy from one location to another. “
