Question

directions: drag each tile the correct box. the pitch of a sound is how high or low it is. the higher the frequency of a sound wave is, the higher its pitch. each of the waves below represents a sound wave. put the waves in order from lowest to highest pitch

Explanation:

Step1: Count the number of cycles

Count the number of complete cycles (from peak - trough - peak) in each wave within the range of \(x = 0\) to \(x=4\).
For the first wave: \(1\) cycle.
For the second wave: \(1.5\) cycles.
For the third wave: \(2.5\) cycles.
For the fourth wave: \(2\) cycles.

Step2: Relate cycles to frequency and pitch

Since frequency (number of cycles per unit time) is related to pitch (higher frequency = higher pitch).
The order of number of cycles from lowest to highest: \(1<1.5 < 2<2.5\)

Answer:

First wave \(<\) Second wave \(<\) Fourth wave \(<\) Third wave
