Question

1. A sound with large amplitude is louder than one with small amplitude.

2. Shortening the string of a guitar lowers its pitch

3.Frequency is the number of vibrations per second.

4 Sound travels fastest in solids.

5. The quality of a sound depends on the frequency of vibration.

6.Inaflute, the longer the air column, the louder the sound.​

Answer 1

Answer:

1 The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

2 Guitar strings are tuned using their tuning keys. Applying too much tension to a string tightly can raise it to the pitch of the next note, while loosening it can easily lower it the same amount.However, if the length of this string is shortened, its pitch will increase.

3 The number of vibrations per second is known as the frequency, measured in Hertz (1 Hz = 1 vibration per second)

4Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it.

5 It depends on the frequency of vibration of the waves. If the frequency of vibration is higher, we say that the sound is shrill and has a high pitch.
