Final answer:
In radio wave interference situations, appropriate clearance must be received from the tower to prevent electromagnetic interference. Different organizations utilize different radio frequency bands to minimize interference between electromagnetic signals from communication systems and everyday gadgets like car keys and TV remotes.
Step-by-step explanation:
Appropriate clearance is required from the tower in radio wave interference situations. This is because different organizations utilize different radio frequency bands to prevent interference between electromagnetic signals. For example, astronomers and astrophysicists need to collect signals from outer space without electromagnetic interference from communication systems and everyday gadgets like car keys and TV remotes.
