Question

Because of barriers and obstructions, you can see only a tiny fraction of a standing wave on a string. You do not know, for instance, how long the string is. All you know is that the speed of waves on the string is 100 m/s and that the distance is 10 cm. Can you determine the frequency of the standing wave? 1. Sure, the frequency is 1000 Hz. 2. Sure, the frequency is 500 Hz.

    Answer:

    500 Hz

    Explanation:

    Given that,

    speed of waves on the string is 100 m/s

    distance is 10 cm

    so given v is 100 m/s and L is 10 cm

    frequency = speed (wave on string) / 2L

    so the frequency is 100/2*10*10^-2m

    = 1000/2

    =500 Hz  

    so the answer is 500 Hz

    frequency = speed (wave on string) / 2L

    so given v is 100 m/s and L is 10 cm  

    so the frequency is 100/2*10*10^-2m

    = 1000/2

    =500 Hz  

    so the answer is 500 Hz

    Answer:

    (1) Sure, the frequency is 1000 Hz.

    Explanation:

    Frequency = wave speed ÷ wave distance

    wave speed = 100 m/s

    wave distance = 10 cm = 10/100 = 0.1 m

    Frequency = 100 ÷ 0.1 = 1000 Hz
