A sound wave traveling at STP has a period of .0023 seconds. The wavelength of this sound is closest to
1)1.4E5
2)6.9E-6
3)0.76m
4)76m

3

Wavelength = 0.76m

Explanation:

When sound wave is travelling at standard temperature and pressure ( STP), its speed will be equal to normal speed of sound which is equal to 331 m/s

Given that the period of the wave is 0.0023 seconds.

Wave speed = wavelength/period

Substitute the wave speed and the period to obtain wavelength

331 = wavelength/0.0023

Cross multiply

Wavelength = 331 × 0.0023

Wavelength = 0.7613 metre

The wavelength of this sound is closest to 0.76 m

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
