Sounds of Music B Question Marathon

Post by Jim_R »

Question Marathon for Sounds of Music B.
-The path of the Administrator is beset on all sides by the inequities of the selfish and the tyranny of evil men.

-Nothing\'s gonna get deleted. We\'re gonna be like three little Fonzies here. And what\'s Fonzie like? Come on, what\'s Fonzie like?
-Cool?
-Correctamundo. And that\'s what we\'re gonna be. We\'re gonna be cool. Now, I\'m gonna count to three, and when I count three, you let go of your mouse, and back away from the keyboard. But when you do it, you do it cool. Ready? One... two... three.

I'll start off.
Two performers are playing the same note at the same time, but slightly out of tune, so that beats are heard in the
sound. If the frequencies are 440 Hz and 446 Hz, how many beats are heard each second?
a) 443 beats / sec
b) 12 beats / sec
c) 6 beats / sec
d) 223 beats / sec

Remember to hide the answer (use [hide] [/hide])

Just for fun...
[hide] 6 beats per second [/hide]

EDIT: Apparently hiding my answer isn't working. Whoops.

Looking forward to anatomy, protein, fossils, and optics (NYS trial) this year!

I am just going to make a new question:
What is an antinode? A node? What is a standing wave pattern?

The anti-node in a wave function is the point that has the highest displacement (amplitude), while nodes are the points of a wave that have minimal to zero displacement. These two points are both typically found in standing waves, which remain in a constant position. Examples of this are guitar strings or xylophone/marimba bars.

Next question: name two environmental factors that can affect the speed of sound.

Temperature, and Wind Conditions?

I was gonna say temperature and altitude, but those really affect it in the same way.

So do I get it right :O. I do see how altitude would affect it as well
