Which statement about data carried on electromagnetic waves is true?(1 point)
Responses

Obstacles such as buildings, trees, or mountains pose no problems for data loss.
Obstacles such as buildings, trees, or mountains pose no problems for data loss.

Data can be lost due to attenuation of the wave.
Data can be lost due to attenuation of the wave.

Data carried on an electromagnetic wave move slower than data carried on a copper wire.
Data carried on an electromagnetic wave move slower than data carried on a copper wire.

The only way to encode the data on an electromagnetic wave is by modifying the wave's amplitude.
