1.Oscillatory motion : this is the to and fro movement of wave signals from the antenna
2.a.Microwave Oven- produces microwaves
b.. Light bulb-produces visible light
3.Radio signals does not pass through a solid barrier in the dark. Just like how light can't pass through a rock. The radio signals are restored as the car gets to the entrance of the tunnel
Explanation:
Waves is a disturbance which travels displacement and transfers energy without displacing the medium itself
Most waves are caused by vibrations. What motion in a transmitting antenna causes the vibrations that produce radio waves?
Oscillatory motion : this is the to and fro movement of wave signals from the antenna
2. Name two common household appliances that produce electromagnetic waves other than radio waves. What kind of electromagnetic waves do they produce?
a.Microwave Oven- produces microwaves
b.. Light bulb-produces visible light
3.When you are in a car and it passes through a tunnel, the radio signal is sometimes lost. Why do you think this happens?
Radio signals does not pass through a solid barrier in the dark. Just like how light can't pass through a rock. The radio signals are restored as the car gets to the entrance of the tunnel
