Understanding Invisible waves

We are constantly being bombarded by invisible waves

Can you think of any examples of invisible waves? Sound, light, radio, heat, cell phone, garage door opener, microwave, etc

All these waves belong to the same category except for … … Sound

The name of this category is … … Electromagnetic waves

What do these waves have in common? 1. They all take time to travel. 2. Once the source of a wave stops, the wave itself keeps going. 3. The distance from one peak to the next is called “wavelength”. 4. They all travel at the speed of light. 5. They all travel through space.

How are these waves different? They have different wavelengths. They have different properties.

What is the difference between these 2 sets of waves?

The End

What is the difference between these 2 waves?

Can you think of any examples of invisible waves? Sound, light, radio, heat, cell phone, garage door opener, microwave, etc What do these waves have in common? Provide at least 3 examples. 1. They all take time to travel. 2. Once the source of a wave stops, the wave itself keeps going. 3. The distance from one peak to the next is called “wavelength”. 4. With the exception of sound, they all travel at the same speed. How are these waves different? They have different wavelengths. They have different properties. Invisible waves that can travel through empty space are known as Electromagnetic Waves The most common example of this is ______________________. Invisible waves that can not travel through empty space are known as ___________________ _____________
