Two train whistles, and , each have a frequency of 392 Hz. is stationary and is moving toward the right (away from ) at a speed
trasher [3.6K]

Answer:

Part a)

f = 371.1 Hz

Part b)

f = 417.7 Hz

Part c)

beat frequency = 46.6 Hz

Explanation:

Part a)

Due to doppler's Effect the frequency of the sound heard by the train which is moving away from the observer is given as

f_1 = f_0\frac{v + v_o}{v + v_s}

f_1 = 392(\frac{340 + 15}{340 + 35})

f_1 = 371.1 Hz

Part b)

Now from the second train which is approaching the person we can say

f_2 = f_0\frac{v - v_o}{v - v_s}

f_2 = 392(\frac{340 - 15}{340 - 35})

f_2 = 417.7 Hz

Part c)

As we know that beat frequency is the difference in the frequency from two sources

f_b = f_2 - f_1

f_b = 417.7 - 371.1 = 46.6 Hz

e-lub [12.9K]

Answer:

The student which is correct is Anya

Explanation:

The wavelength of a wave is the length of one complete wave cycle and it is represented by Greek letter lambda (λ)

The frequency of a wave is the number of waves (complete wave cycles) passing a given point over a given time period and the frequency is represented by the Greek letter nu (ν) and also as "f" (which is the first letter of the word "frequency")

Therefore, the speed, "v", (different from nu (ν)) of the wave is given as follows;

v = f × λ

From which we have;

λ = v/f

∴ λ ∝ 1/f

Which indicates an inversely proportional relationship between the wavelength and the frequenct

From which we have that as the wavelength decreases, the frequency increases

Therefore, Anya decrease increase is correct
