Sample questions

1. 1.How is a sound wave produced in a string that is fixed at both ends?
   • A.By generating longitudinal waves directly in the string that travel to the ear.
   • B.By creating transverse vibrations that reflect at fixed ends, forming standing waves which produce longitudinal waves in air.
   • C.By striking the string to produce only transverse waves that reach the ear directly.
   • D.By plucking the string to create sound waves that do not reflect at the ends.
2. 2.In a hospital, an ultrasonic scanner is used to locate tumours in a tissue. What is the wavelength of sound in a tissue in which the speed of sound is $1.7 \mathrm{~km} \mathrm{~s}^{-1}$? The operating frequency of the scanner is $4.2 \mathrm{MHz}$.
3. 3.The voice of women is shrill as compared to men because of the difference in their :
   • A.speed
   • B.frequency
   • C.loudness
   • D.all these
4. 4.Which graph correctly represents the displacement from the mean position versus time for a body executing free vibration in a vacuum?
   • A.A sinusoidal wave with constant amplitude and frequency
   • B.A sinusoidal wave with decreasing amplitude over time
   • C.A straight line with a positive slope
   • D.A parabolic curve with increasing amplitude
5. 5.When a bell rings in air, what type of waves are produced? A string vibrates with a frequency of 500 Hz. If the distance between two consecutive troughs of a transverse wave produced in the string is 20 cm, what is the velocity of the wave?
   • A.50 m s⁻¹
   • B.100 m s⁻¹
   • C.200 m s⁻¹
   • D.500 m s⁻¹
