  2. 2Label the marked spots on the diagram belowImage for question 2
    1. Acompression
    2. Brarefaction
  3. 3Label the picture belowImage for question 3
    1. Awavelength
  4. 4What will you HEAR differently if the wavelength increases?
    1. AThe pitch will increase
    2. BThe pitch will decrease
    3. CThe frequency will increase
    4. DThe frequency will decrease
    5. EThe loudness will increase
    6. FThe loudness will decrease
  5. 5The frequency limit of a human is between [blank_start]20[blank_end] and [blank_start]20000[blank_end] Hz
    1. A20
    2. B20000
  6. 6Echoes are:
    1. ARefraction of sound
    2. BReflection of sound
    3. CTotal internal reflection of sound
    4. DDiffraction of sound
  7. 7This wave is [blank_start]3[blank_end] Hz because it has [blank_start]3[blank_end] waves in [blank_start]1[blank_end] second (write in numbers not letters)Image for question 7
    1. A3
    2. B3
    3. C1
  8. 8The wavelength is the vertical distance from the equilibrium (middle)
    1. ATrue
    2. BFalse
  9. 9Sound travels when the molecules in the [blank_start]medium[blank_end] vibrates. The closer the molecules are, the [blank_start]faster[blank_end] sound travels. The fastest medium is a [blank_start]solid[blank_end] while sound does not travel in a [blank_start]vacuum[blank_end]. In the ear, a vibrating object e.g. a trumpet produces waves. Sound then travels from the [blank_start]medium[blank_end] (air) to the ear. The vibrating air enters the ear, fuelled to the [blank_start]ear canal[blank_end]. The vibrating air sets up vibrations in the [blank_start]ear drums[blank_end]. The ear drums then transmit the vibrations to the small bones called [blank_start]ossicles[blank_end], causing them to vibrate. The [blank_start]cochlea[blank_end] vibrates. These vibrations are detected by the hair lining and the [blank_start]auditory nerve[blank_end] will then detect these vibrations and send the impulses to the brain.

    38. ALauditory nerve
    39. AMauditory nerve
    40. ANcochlea
    41. AOear drums
    42. APossicles
    43. AQear canal
  10. 10An echo sounder ship is tested where the sea bed is known to be 60 m deep. The time between sending each ultrasonic pulse and receiving its echo was measured at 0.1s. The time for the ultrasonic wave to reach the sea bed is [blank_start]0.05[blank_end] s. To find the speed, we have to use the equation speed = distance/time, so [blank_start]60[blank_end] division by [blank_start]0.05[blank_end]= [blank_start]1200[blank_end] m/s.
    1. A0.05
    2. B60
    3. C0.05
    4. D1200
