How do TV waves propagate Do they pass through geography and buildings or do they bounce from transmission source to the ionosphere and back down as in reflected or straight line of sight?

Ideally they should travel from the transmitter directly to the receiver (line of sight). But in reality, they travel in all the ways you mentioned - direct (line of sight), through buildings and obstacles, they bounce off the ground and other objects (including the atomosphere) and then eventually arrive at the receiver.

TV waves propagate through a combination of direct line-of-sight transmission and reflection. When transmitted, the waves travel through the atmosphere and may bounce off the ionosphere or reflect off buildings and geography before reaching antennas on the ground. The ionosphere can help extend the range of the transmission by reflecting the waves back toward the Earth's surface.

Why normal waves are different to tsunamis?
Normal waves are caused by the wind's energy transferring to the water surface and are relatively small in height and wavelength. Tsunamis, on the other hand, are generated by disturbances such as underwater earthquakes or volcanic eruptions which displace large volumes of water, creating powerful, long-period waves that can travel thousands of kilometers across the ocean. Tsunamis can cause devastating impact when they reach coastal areas due to their energy and height.
What vegetation is the characteristic of the South?
The South is known for its diverse vegetation, including longleaf pine forests, magnolia trees, live oaks, and azalea bushes. These vegetation types thrive in the warm and humid climate of the region.
What is the difference between sound and visiblle light in transmission?
Sound will propagate through any matter, but not a vacuum, light will propagate through a vacuum, but only through transparent matter.

What is the speed of gravitiy?
Gravitational waves propagate at the speed of light. Any change in the distribution of masses will propagate at that speed.
What do light waves propagate through?
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.
Where does sound not propagate?
sound needs a material medium to travel. Sound can travel by compression and rarefactions.attma
What role do dendrites play in transmission at chemical synapses?
Dendrites are the beginning of action potentials as they are formed and then propagate through a neuron. At the synapse, the dendrites receive the incoming signal from neurotransmitters released at the terminal of the previous neuron.
