Question

Скорость первой волны в 2 раза больше чем второй,Во сколько раз больше частота второй волны если ее длина в 3 раза меньше чем длина первой волны

Answer 1

Частота второй волны в 3 раза больше, чем первой.

Answer 2

Calculation of Wave Frequency Ratio

To calculate the frequency ratio of the second wave when its length is three times smaller than the length of the first wave, we can use the formula:

Frequency = Speed / Wavelength

Given: - Speed of the first wave = 1200 - Speed of the second wave = 600 (since the first wave is twice as fast as the second) - Length of the first wave = 3 - Length of the second wave = 1 (since it's three times smaller than the first wave)

Using the formula, we can calculate the frequency of the second wave:

Frequency of the first wave (f1) = Speed / Wavelength = 1200 / 3 = 400 Frequency of the second wave (f2) = Speed / Wavelength = 600 / 1 = 600

So, the frequency of the second wave is 600, which is 1.5 times greater than the frequency of the first wave.

This calculation is based on the provided speed and length values and the formula for wave frequency.
