טקסט Storyboard
Remote control is one of the example of infrared. Its wavelength is longer than visible light.
Did you know when you watch tv you are using EM waves?
Oh really? Can you tell me more about EM waves?
Radio is one of the example of radio wave.
It is the longest wavelength in EM waves and at lower frequency than microwave.
What is radio wave?
You mentioned microwave, what is microwave in EM waves?
Microwave is the second longest wavelength in EM waves and it has a low energy.
It is commonly used for the preparation of food, satallite, phones and medical treatments.
Light bulbs and fluorescent bulbs are examples of visible light.
Visible light is one of the portion in EM waves that visible or can be seen by the human eye.
How did light and fluorescent bulbs are examples of visible light? What is visible light?
What are we doing here?
What is UV wave?
UV wave has a longer wavelength than x-ray but shorter than visible light. It also has high frequency and energy.
Sunlight is the main source of UV wave.
I know that! it's x-ray. It used to check the bones and to look for breast cancer.
Thank you! I learned a lot about EM waves and its different wavelength, frequency and energy.
The last one is Gamma ray that has a smallest wavelength but has a highest frequency and energy in EM waves.
Yes you're right, x-ray has a short wavelength but has a high frequency and energy.
