Unknown Story

Hi, I'm Alexa, I am 14 years old and I'm in 8th grade
Every night I help my mom to cook the dinner.
All saturdays I like to see TV with my family
In the school in physics class we saw the theme of electromagnetic waves. So, let's go ahead and I'll show you how I used them in my house
When I get bored I grab a CD and a flashlight to light up the CD and form this that I learned in physics
When I use the stove I used the radio waves. This type of wave have the longest wavelengths and the lowest frequencies; wavelengths range from1000s of meters to .001 m.
I remember that before the pandemic, my mom went to the hospital to get an X-ray. The result of the x-ray showed that my mother had cancer and she started with the treatments.
When I on the TV with the control, I use the Infrared waves that the control do when I hit the button "on". This type of wave the human eye cannot see it, but humans can detect it as heat.
Cousin, since we finish the assignments, do you want to play outside?
This type of wave is called visible light, and is the one that the human eye is capable of perceiving.
The X-Rays are another type waves and these rays have enough energy to penetrate deep into tissues and cause damage to cells. Also GammaRays are in this part and it use to the treatments of cancer.
Ultraviolet light is another type of wave and it comes from the sun.
