A tuning fork vibrates at a frequency of 250Hz. Now temperature rise from 0 C to 20C what is the change in wavelength Share with your friends Share 1 Tejan Gupta answered this $Dearstudent,\phantom{\rule{0ex}{0ex}}Velocityat{20}^{o}C=331\sqrt{\frac{293}{273}}=342.3m/s\phantom{\rule{0ex}{0ex}}velocity=frequency\times wavelength\phantom{\rule{0ex}{0ex}}wavelength=\frac{342.3}{250}=1.36m\phantom{\rule{0ex}{0ex}}Regards$ 0 View Full Answer
