. Length of a string tied to two rigid supports is 40 cm
Maximum wavelength (in cm ) of a stationary wave produced on it is
A: 20
B: 80
C: 40
D: 120
Best Answer
Explanation:
Given the length (L)=40cm.
Let the wavelength be λ.
Now, it is known that
L=λ/2
⇒40=λ/2
⇒λ=40×2=80cm
So, option (B) is the correct option.
Final Answer:
Hence, option (B) is the correct option.i.e 80cm
