What is the wavelength of a sound wave with a frequency of 50 Hz and a speed of 340 m/s?

Heya!!

For calculate wavelength, lets applicate formula:

                                                   Δ   Being   Δ

                                            f = Frequency = 50 Hz

                                            v = Velocity = 340 m/s

                                              = Wavelenght = ?

⇒ Let's replace according the formula:

⇒ Resolving

Result:

The wavelength is 6,8 meters.

Good Luck!!

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
