Sound and hearing quiz

15 Questions

Quiz Description

In this quiz, we will be looking into sound and hearing which are always going to be a pair. We only perceive sound with our ears by hearing. Sound is very essential to us humans, it is important because it can tell us about character, place, and time, it informs us and moves us in ways visuals can't, and because certain combinations of sound and visuals can evoke what neither can do alone. It's also potentially important because it can help to determine what we see after all these are fulfilled, we can say we heard a sound. This quiz will teach you lessons like, what sound is, characteristics of sounds, hearing, the relationship between hearing and sound, and even more. 

Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid, or solid. It is created when something vibrates and sends waves of energy (vibration) into our ears. It is a wave and all waves are characterized by their ability to undergo reflection, refraction, diffraction, and interference, and all waves have a wavelength, frequency, speed and amplitude You will see more along the quiz.

Note that this physics quiz will not only help you academically but will help boost your knowledge of the ear and how we come to perceive sounds of different melodies, pitch, frequency, etc, and why we also do so. For example, sounds from a piano, guitar, and xylophone are all 3 different sounds with different quality and timbre.
It is therefore necessary for you to take these quizzes where you will be having MCQs with provided answers and only one of the four options will be correct.
Good luck! 

1:

A steel wire was mounted on a board, so that the left hand bridge position could be changed, but fixed with an adjusting screw on the right to vary the tension on the wire. The wire thickness and length, its tension (tightness) and force applied can be varied to change the 'character' of the sound produced on plucking the wire. Which change will produce a higher pitched note in the wire sound?


Correct
  • 1:
     longer wire
  • 2:
     slacker wire
  • 3:
      plucking harder
  • 4:
     thinner wire

    gases
  • 2:
    solids
