The transmitting and receiving vibrators are mutually perpendicular. Will vibrations occur in the receiving vibrator?

Oscillations will not occur. The vibrator emits waves in which the vector of the electric field strength belongs to the axis of the vibrator. The maximum radiation intensity is in the direction perpendicular to this axis. If the second vibrator is perpendicular to the first, emitting waves, then the projection of the electric field strength on the axis of the second vibrator is zero, therefore, oscillations will not occur in it.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
