A string of length

1 \mathrm{~m}

and mass

5 \mathrm{~g}

is fixed at both ends. The tension in the string is

8.0 \mathrm{~N}

. The string is set into vibration using an external vibrator of frequency

100 \mathrm{~Hz}

. The separation between successive nodes on the string in

\mathrm{cm}

is close to

View answer and explanation

Correct option: A

Option A (20) is correct because the separation between successive nodes is half the wavelength, and the wavelength can be calculated from the given frequency and wave speed.

A mercury column of length 0.1m is filled in its middle and in rest two parts air is filled at atmospheric pressure. When tube is turned to vertical position, then displacement of mercury will be (standard pressure = 0.76 m of Hg) A tuning fork produces waves in a medium. If the temperature of the medium changes, then which of the following will change In a stationary wave all the particles A SONAR system fixed in a submarine operates at a frequency
