Sonometer
 1) What happens when the wavelength of a wave increases? Its frequency increases Frequency decreases Amplitude decreases No change in any other parameters

 2) In order to form stationary waves, the two individual waves should have which of the following characteristics? Same frequency, amplitude and velocity, travelling in opposite direction. Same frequency, amplitude and velocity, travelling in any direction. Same frequency, amplitude and velocity, travelling in same direction. Same amplitude and velocity, travelling in opposite direction

 3) Which of the following relation is correct for a stretched string under vibration? Both a and b None of these Length of the string is directly proportional to Tension Frequency is directly proportional to the linear density of string

 4) Two stretched strings of same material are vibrating under same tension in fundamental mode. If the ratio between their radii is 1:3 and that between lengths is 1:2, then what will be the ratio between their frequencies? 6:1 1:3 3:1 1:6

 5) What is the type of waves produced in stretched strings under vibration? Either longitudinal or transverse waves None of these Longitudinal waves Transverse waves

 6) In a sonometer experiment, what change occurs when the tension doubles? Resonant length doubles No change occurs None of these Frequency reduces to its half

 7) What happen when the paper rider in the sonometer experiment flies off? Frequency of wire between the bridges becomes much greater than that of the tuning fork. Frequency of wire between the bridges becomes zero. Frequency of the wire between the bridges and the tuning fork are exactly equal. Frequency of wire between the bridges becomes much less than that of the tuning fork.

 8) Choose the correct relation to explain the Law of length of a stretched string. ν ∝ l , for constant mass and tension ν ∝ 1/l , for constant tension ν ∝ 1/l , for constant mass and tension ν ∝ l , for constant tension

 9) Nodes are regions of standing waves in which the particles in the medium have which of the following? Minimum strain Zero displacement Very small displacement Maximum displacement

 10) Which is the correct relation, if two bodies are in resonance with frequencies ν1 and ν2 respectively? ν1 > ν2 ν1 ∝ ν2 ν1 = ν2
