Question

7) You now set up a standing wave pattern of the 2nd harmonic. How did the velocity change? increase remain the same decrease 8) How did the frequency change? increase remain the same decrease 9) How did the wavelength change? increase remain the same decrease 10) Which property of waves allows you to hear someone talking around the corner of a building? refractiorn diffraction interference dispersion the doppler effect 11) Which property of waves allows you to hear beats when tuning an instrument? refractiorn diffraction interference dispersion the doppler effect

Explanation / Answer

7) remains same

Because speed depends on medium

8) increase

Because wavelength decreases

9) decrease?

10) diffraction

Bending of wave around corners is called diffraction

11) interference

Beat is time dependent interference
