Homework Statement A tuning fork with a frequency of 420 Hz emits sound with a wavelength of 0.82 m in air. If the temperature of the air increases, what will happen to the wavelength and why? Homework Equations The Attempt at a Solution I know temperature affects speed but I am not so sure...

Thanks so much for your help, mgkii :)

Thank you so much for your help! I really appreciate it! :biggrin:

Ok. So before the bands were added the possible frequencies were 322 Hz and 318 Hz. So I'm assuming the original frequency would be 322 Hz. I'm assuming this because 321 Hz was the right frequency for after the bands were added, so since 321 Hz came from decreasing 322 Hz by 1, I would assume...

The rate of vibration would decrease. So I re-did my answer and it makes a lot more sense than the previous one. Here goes: fb = N/ Δt fb = 14 / 7.0s = 2.0 Hz f2 = f1 ± fb f2 = 320 Hz ± 2.0 Hz = 322 Hz or 318 Hz Because of the elastic band on Tuning Fork B, the frequency will decrease...

Homework Statement Tuning Fork A has frequency of 320 Hz. When it is sounded with Tuning Fork B, 14 beats are detected in 7.0 seconds. Elastic bands are placed on the tines of Tuning Fork B and the beat frequency drops down to 1.0 Hz. What was the original frequency of Tuning Fork B? Explain...

Homework Statement A boat is floating at rest in dense fog near a cliff. The captain sounds a horn at water level and the sound travels through the salt water (1470 m/s) and the air (340 m/s) simultaneously. The echo in the water takes 0.40s to return. How much additional time will it take the...
