Did you know...

~~ That the speed of sound varies depending on the temperature. The higher the temperature, the faster the speed of sound.

~~ "White Noise - all values of the sound waves are completely random."

~~ "Sound waves are significantly larger than light wavelengths. This explains why people can hear sounds around corners but cannot see objects around them." :-P

~~ Music is math and I've gotta live with it.

~~ Everything is effing Physics.

Hearing or seeing around corners is all about reflection. There are some corners you can't hear around, and some you can see around (mirrors would let you see an object, but ordinary walls will reflect scattered light).

However, there are also radio waves that are electromagnetic radiation at such long wavelengths that they can go THROUGH walls. Here's a question - how do radio wavelengths compare to those of sound? What note has the same wavelength as 89.7 WITR's FM signal at room temperature? :)

Radio waves are transverse waves.
Sound waves are longitudial waves.

They can't be compared the way you want to compare them.

Yeah, I know sound waves are compression waves and that EMR waves are the other kind but forgot what it's called. Anyway... Waves of either kind have a period and a frequency. If there is a period and frequency, there is a wavelength. The doppler effect standing next to a highway would prove this: closing the distance decreases the apparent wavelength.
