It's hard to tell but that little dot in the sky is not a balloon, it's the moon. The moon, as I hope you all know, does not create its own light but rather reflects the light of the sun. The moon is a nice white color but has blotches on it. The whiteness comes from the moon's rocks, which reflect all visible frequencies of light as there is no reason for them not to. The blotches though are made by huge craters in the moon where no light goes inside. Thus, they remain black. So ya, the moon is beautiful.

The Moon is Beautiful
In case you don't understand the reference for the title, it's a line from the song "Oh Yeah" by the band Yello. I'm sure you've heard it somewhere. Anyways, this chapter, we're learning about electromagnetic waves and have been focusing on light so far. While I was out and about yesterday, I spotted the moon shining at around 5 P.M. and thought that was neat.

Sound
Sorry but this is a lame blog post. Didn't have much time to do anything this weekend so all i could think of was the sound equalizer on my cell phone which looks like this:
It's hard to see but all those bars have a number under them. 80 and 420 Hz and 1.4 and 3.7 kH. These are measures of frequency and thus also measures of wavelength (tone) as they are inversely related. I can change the levels of different frequencies in this way and change the sound of whatever i'm listening to. That's it.
