Respuesta :
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
The explanation of how materials that are good conductors have a molecular structure that aids designing more efficient technologies has been explained below.
- Good conductors are materials that can conduct electricity very well.
- Now, an example of materials that are good conductors of electricity are metals. This is due to the fact that inside their structures, they possess free electrons that enable them to move freely within the metals which means there is a very good flow of electricity.
- Now, In terms of being helpful to engineers, it's very useful especially when making powerful batteries. This is because good batteries means amount of electricity it can store will be much and as such it will last for a long time.
