Amusician increases the wavelenght of the sound waves she produces without changing their speed. what must be happening to their frequency of the waves?

The frequency of the waves must decrease when the musician increases the wavelength without changing their speed.

Explanation:

Wavelength is the distance over which the wave's shape repeats, as can be seen in the attached figure:

The speed (v), refers to the rate at which the wave propagates in space.

The frequency (f) is the number of waves that pass a given point in an amount of time. It could be defined mathematically as follows:

As we can see in the previews equation, the frequency is inversely proportional to the wavelength, thus if we increase the wavelength with a constant speed, we obtain a reduction in the frequency

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
