Sample questions
-
1.A transducer transmits and detects ultrasonic waves as shown in the figure. The waves reflect off the sea floor and return to the transducer. The speed of the waves is 1500 m/s, and the time between transmission and reception is 48 milliseconds. What is the depth of water, D, in the figure?
- A.18 m
- B.36 m
- C.72 m
- D.144 m
-
2.Sometimes when a vehicle is driven at a particular speed, a rattling sound is heard. What is the name of the phenomenon responsible for this sound?
- A.Doppler effect
- B.Resonance
- C.Interference
- D.Echo
-
3.When the tuning fork in the figure below is made to vibrate, how does the pattern of the coils of the spring change?
- A.The coils remain evenly spaced with no visible change.
- B.The coils exhibit a wave pattern with compressions and rarefactions.
- C.The coils stretch uniformly along the entire length of the spring.
- D.The coils twist into a spiral pattern due to rotational motion.
-
4.A man fires a gun and hears its echo after $5\mathrm{s}$. The man then moves $310\mathrm{m}$ towards the hill and fires his gun again. This time he hears the echo after $3\mathrm{s}$. Calculate the speed of the sound.
-
5.A wire of length $80\,\mathrm{cm}$ has a frequency of $256\,\mathrm{Hz}$. Calculate the length of a similar wire under similar tension, which will have frequency $1024\,\mathrm{Hz}$.
