The phase angle between two points is 3π. The distance between these points is 15 cm. What is the wavelength of the wave?
- A
30 cm
- B
45 cm
- C
5 cm
- D
10 cm
Phase difference = 21π/λ x
distance between the two points
Therefore:
3π = 27π/λ × 15
3 = 30/λ
λ = 30/3
= 10 cm
As it is numerical so it can have only one possible answer.
