Science Common Sense
1451 - What is an example of electromagnetic waves transmitting energy, such as using a mobile phone
When you use a mobile phone, you're sending and receiving electromagnetic waves. Here's how it works:
- When you make a call or send a text, your phone converts your voice or message into a type of electromagnetic wave called radio waves.
- These radio waves have a specific frequency (think of it like a special address) that helps the signal reach the right tower.
- The radio waves travel through the air to the nearest cell tower.
- The cell tower receives the radio waves and sends them to the person you're trying to contact.
- The person's phone receives the radio waves and converts them back into sound or text, so they can hear or read your message.
In this example, the electromagnetic waves (radio waves) are transmitting energy (your voice or message) from one place to another, without having to touch or connect anything directly. It's like magic, but it's actually science!
