- "Look here at this beautiful sunny day. A perfect 77℉ (25℃). If you use the formula c=331.3+ 0.6(t) it will give you the speed of sound if you were to hear something out there. For this sunny scene it would be:c=331.3+ 0.6(25) = 364.3 m/s. "
- Good afternoon Chicagoland area. We've got some news tonight informing more people about wavelengths..
- BREAKING NEWS
- You know Michael not too many people know enough about wavelengths. How about how frequency is inversely related to wavelengths?
- BREAKING NEWS
- I totally agree with you Steve. Did you know you can even find the wavelength from the formula ƛ=c/f?
- Wow! How interesting. While speaking of (c) th speed of sound, Did you know that temperature has an effect on it?
- BREAKING NEWS
- I had no idea, do you mind explaining it for me?
- Now in this chilly scenery with average temps of -31℉ (-35℃), the speed of sound moves a lot slower.c- 331.3+ 0.6(-35) = 310.3 m/s.A lot slower than the hot sunny day. This is due to how fast air molecules move with heat, compared to cold temperatures that make it slow down.
- BREAKING NEWS
- It's no problem. This wraps us up for tonight, see you tomorrow at 9. Now to the weather.
- Wow thank you for explaining that Steve, that is so interesting!
