Question

Скорость механической волны 400м/с ее частота 6кило Гц.Определить длину волны и период колебаний???

Answer 1

V=L*v
L=V/v=400/6000=0,07 м
T=1/v=1/6000=1,67*10^-4 c

Answer 2

Calculation of Wavelength and Period

To determine the wavelength and period of a mechanical wave with a speed of 400 m/s and a frequency of 6 kHz, we can use the formulas:

Wavelength (λ) = Speed (v) / Frequency (f)

Period (T) = 1 / Frequency (f)

Let's calculate the values:

1. Wavelength (λ): - Speed (v) = 400 m/s - Frequency (f) = 6 kHz = 6000 Hz

Using the formula, we can calculate the wavelength:

Wavelength (λ) = 400 m/s / 6000 Hz

To convert Hz to kHz, we divide by 1000:

Wavelength (λ) = 400 m/s / 6 kHz = 0.0667 m

Therefore, the wavelength of the mechanical wave is approximately 0.0667 meters.

2. Period (T): - Frequency (f) = 6 kHz = 6000 Hz

Using the formula, we can calculate the period:

Period (T) = 1 / 6000 Hz

Period (T) = 0.0001667 seconds

Therefore, the period of the mechanical wave is approximately 0.0001667 seconds.

So, the wavelength of the wave is approximately 0.0667 meters, and the period of the wave is approximately 0.0001667 seconds.

Please note that the calculations are based on the given values and formulas.
