. 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
