Sound is produced by (a)
Which of the following is not a property of sound waves?
longitudinal wave
able to propagate through vacuum
propagate at different speed in different medium
travels the fastest in solid
Name the part of a longitudinal wave where particles are close to each other and has higher pressure.
(a)
What is human hearing range?
200 Hz - 20 000 Hz
2 Hz - 2000 Hz
20 Hz - 20 000 Hz
200 Hz - 2000 Hz
Which of the following animal has the widest hearing range?
Dog
Cat
Beluga whale
Dolphin
Which of the following sequence is correct to represent the increasing speed of sound?
Solid ➝ Liquid ➝ Gas
Liquid ➝ Gas ➝ Solid
Gas ➝ Liquid ➝ Solid
Liquid ➝ Solid ➝ Gas
Which of the followings are the typical speed of sound in solids?
343 m/s
1500 m/s
5950 m/s
5890 m/s
Why the speed of sound in gas is the slowest?
Gas particles are far apart so there is time delay to transfer vibration.
Most of the sound wave is lost and absorbed by surrounding.
Gas has less density compared to solid and liquid
Mass of gas is heavier than solid and liquid.
Which of the followings are sound absorbers?
What is the term used to name the reflected sound waves?
(a)
A ship uses SONAR to determine the depth of a group of fish. The time taken for the ship to detect the echo is 4 seconds. If speed of sound in water is 1500 m/s, calculate the depth of the fish.
0.003 m
375 m
6000 m
3000 m
The pitch of a sound wave depends on its (a)
Amplitude of a sound wave is increased as shown. What happens to the new sound wave?
The new sound becomes softer.
The new sound becomes louder.
The new sound has lower pitch.
The new sound has higher pitch.
