Answer 1

426

Step-by-step explanation:

Answer 2

426 Hertz

Step-by-step explanation:

We are given;

• The velocity of the wave as 341 m/s
• Wavelength as 0.8 meters

We are required to calculate the frequency of the wave.

• We need to know that the velocity of a wave is the product of frequency and wavelength.

• That is;

Velocity = frequency × wavelength

• Rearranging the formula;

Frequency = Velocity ÷ wavelength

Therefore;

Frequency = 341 m/s ÷ 0.8 m

= 426.25 Hertz

= 426 Hertz

Thus, the frequency of the wave is 426 Hertz
