Answer:
its 1
Explanation:
cuz the ratio between 50:51 and 250:255.so because of its equivalence its right.......mark me as brainlist
Answer :
Two organ pipes each closed at one end gives 5 beat per second.
Ratio of lengths = 50 : 51
We have to find fundamental frequencies of each organ pipe
Let fundamental frequency of pipe 1 be f₁ and that of pipe B be f₂.
⭆ f₁ - f₂ = no. of beats per second
⭆ f₁ - f₂ = 5 ..... (I)
➤ Law of length, f₁ × L₁ = f₂ × L₂
ATQ, L₁/L₂ = 50/51
⭆ f₂/f₁ = L₁/L₂ = 50/51
⭆ f₂ = (50/51) f₁ ..... (II)
Substituting (II) in (I), we get
➠ f₁ - f₂ = 5
➠ f₁ - (50/51)f₁ = 5
➠ f₁/51 = 5
➠ f₁ = 255 Hz
From equation (I)
➠ f₁ - f₂ = 5
➠ f₂ = 255 - 5
➠ f₂ = 250 Hz
∴ (B) is the correct answer.
Cheers!
