Very High Frequency (VHF) has -
1) shorter wavelengths
2) shortest wavelengths
3) longer wavelengths
4) longest wavelengths

What are the three longest wavelengths for standing waves on a270-cm-long string that is fixed at both ends?

? (wavelength) = ( ) m

If the frequency of the second-longest wavelength in part a is 50.0, what is the frequency of the third-longest wavelength?

f = ( ) Hz

a.) What are the three longest wavelengths for standing waves on a240-cm-long string that is fixed at both ends?
b.) If the frequency of the second-longest wavelength is 50 Hz,what is the frequency of the third-longest wavelength?
