Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.

Question

A loudspeaker is placed between two observers who are 110 m apart, along the line
connecting them. If observer 1 records a sound level of 80 dB, what is the sound
