For stationary wave, y = 12 ( x 10 ) (36 t) cm, the distance between a node and the successive antinode is

Options

A20 cm
B12 cm
C10 cm
D5 cm

Correct answer

D. 5 cm

Step-by-step solution

The given equation of the stationary wave is y = 12 ( x 10 ) (36 t) cm. Comparing this with the standard equation of a stationary wave y = A (kx) ( t) , we get: k = 10 Since k = 2 , we have: 2 = 10 = 20 cm The distance between a node and the successive antinode is given by 4 . Distance = 20 4 = 5 cm.
