Question

1 2:12 PM live.hssu.edu MetroPCS LTE 3) Which of the following is a measure of the frequency of a wave? O decibel hertz meter 4) Sound waves travel fastest in (2pts) O liquids. O gas-liquid combinations solids. O gases. ) Which one or more of the following effects occur in all type: wave? O refraction O reflection O diffraction the Doppler effect All of the above 6) A decrease in amplitude of a sound wave means it has a 2pts) lower wavelength. O decibel time period O speed. 7) A pure musical note causes a thin wooden panel nearby to vibrate with the same frequency. This is an example of an overtone. doppler O resonance. 8) The brightness of light is related to (2pts)

Explanation / Answer

3- hertz (unit of frequency)

4-solids (nearer the molecules faster the speed of sound)

5-Diffraction

6-Decibel (Intensity of sound decreases)

7-Resonance ( due to resonance)

8-Amplitude of light is related to intensity also known as brightness of light
