1. the lowest point of a wave is called

the ____________.

1. if you increase the amplitude of a

sound wave, the sound will be

1. the unit for measuring frequency is

____________ (hz).

Explanation:

Question 1

In wave terminology, the lowest point of a wave is defined as the trough. From the word bank, "trough" matches this definition.

Amplitude of a sound wave is related to its loudness. Increasing amplitude makes the sound louder. From the word bank, "louder" is the correct term.

The unit for measuring frequency is hertz (Hz). From the word bank, "hertz" is the term that fits as the unit for frequency.

Answer:

trough
