A stationary wave is formed having 3 nodes along the length of the string 90 cm . The wavelength of the wave is
- A 60 cm
- B 75 cm
- C 90 cm
- D 30 cm
Answer & Solution
Correct Answer
(C) 90 cm
Step-by-step Solution
Detailed explanation
Distance between successive nodes will be 45 cm .
This is equal to \(\frac{\lambda}{2}\).
\(\therefore \quad \lambda=90 \mathrm{~cm}\)
