• What is simple harmonic motion? What is necessary condition for a body to execute simple harmonic motion?
• Think of several examples in everyday life of motion that are simple harmonic?
• What are damped oscillations? How damping progressively reduces the amplitude of oscillation?
• How can you define the term wave? Elaborate the difference between mechanical and electromagnetic waves?
• You can also download the chapter wise test of physics class 10 pdf urdu medium for free.
• Distinguish between longitudinal and transverse waves.
• What is wave equation? Derive relation between velocity, frequency, and wavelength of a wave.
• Does increasing the frequency of wave also increases its wavelength? If yes, how are these quantities related?
• Sound is form of Energy OR Which form of energy sound is: (A)  Electrical   (B)  Mechanical   (C)  Thermal  (D)  Chemical
• For simple pendulum the formula of time period is: (A) T=2π√(m/g)  (B) T=2π√(g/1)   (C)  T=2π√(1/g)  (D) T=2π√(m/k)
• Which of the following characteristics of a wave is independent of others? (A) Amplitude  (B) Wavelength (C)  Frequency  (D) Speed
• Two consecutive waves compression and Rarefaction is called: (A) Focal length   (B) Frequency  (C)  Wave length  (D) Time Period
• The example of longitudinal waves is: (A) Sound waves   (B) Water Waves  (C)  Radio Waves  (D) Light waves
• Which of the waves consist of compressions and rarefactions? (A) Television waves   (B) X-rays   (C)  Sound waves  (D) Radio waves
• The sensation of sound persists in our mind for about:  (A) 0.2 s   (B) 0.02 s   (C)  0.1 s  (D) 0.01s
• To hear a clear echo, the time interval between our sound and the reflected sound must be at least:  (A) 0.2 s   (B) 0.02 s   (C)  0.1 s  (D) 0.01s
• Speed of sound in air:  (A) 2162 Km/h   (B) 1246 km/h   (C)  1262 Km/h  (D) 1264 km/h
• Calculate the frequency of sound wave of speed 340 m/s and wavelength 0.5 m? (A) 680 Hz  (B) 340 Hz   (C)  170 Hz   (D) 0.5 Hz
• What is the necessary condition for the production of sound?
• The sensation of sound produce on our ear only when an object vibrates about its mean position. So the necessary condition for the production of sound is vibration of a body.
• What is the effect of the medium on the speed of sound? In which medium sound travels faster: air, solid or liquid?
• Sound requires medium for its propagation so medium will affect the speed of sound.  Denser medium transmit energy more quickly as compared to rare medium. So speed of sound is more in solids as compared to liquid and gases.
• How can you prove the mechanical nature of sound by a simple experiment?
• Take a jar with a hole at the bottom. Attach a vacuum pump at the bottom of the jar and put a bell inside the jar. Close the jar with a cork and attach the bell with the battery. Bell will start ringing and you will hear the sound. 
• Now start releasing the air through vacuum pump. The sound will become feeble as the air is removes from the jar and when all the air is removed from the jar you will hear no sound. It proves that sound waves are mechanical waves.
