1. The minimum frequency limit of human hearing is 20Hz. If the speed of the sound is 345m/s, what is the wavelength of this in meters?

2. The maximum frequency limit of human hearing is 20000Hz. If the speed of sound is 345m/s, what is the wavelength of this in meters?

3. How fast do waves move if the wavelength is 10m and its frequency is 110Hz?

Answer:

1. [tex]17.25 m[/tex]

2. [tex]0.01725m[/tex] [tex]=[/tex] [tex]0.02m[/tex]

3. [tex]1,100m/s[/tex]

Explanation:

Remember these following formulas:

Asked: wavelength

Formula: wavelength = m (meter) ÷ Hz (Hertz)

Asked: Hz (Hertz)

Formula: Hz (Hertz) = m (meter) ÷ wavelength

Asked: m (meter)

Formula: Hz (Hertz) × wavelength
