Answer:

1. The Speed is 390

2. The Frequency is 425 Hz

3. The Wavelength is 1.3

Explanation:

1. To find the speed of a wave you have to do the formula of speed.

Speed = Wavelength x Wave Frequency.

Speed = 1.5 * 260

= 390

2.

Formula

F= [tex]\frac{1}{T}\\[/tex]

F = 340 / 0.8

= 425

3.

Formula

Wavelength = speed / frequency

Wavelength = 440 / 344   (rounded to nearest tenth if necessary)

= 1.3

Answer:1. The Speed is 390

2. The Frequency is 425 Hz

3. The Wavelength is 1.3

Explanation:

1. To find the speed of a wave you have to do the formula of speed.

Speed = Wavelength x Wave Frequency.

Speed = 1.5 * 260

= 390
