The following equation represent progressive transverse waves
z1 = A cos (ω t – kx)
z2 = A cos (ω t + kx)
z3 = A cos (ω t + ky)
z4 = A cos( 2ω t – 2ky)
A stationary wave will be formed by superposing
A
z1 and z2
B
z1 and z4
C
z2 and z3
D
z3 and z4
Answer
z1 and z2
Explanation
Solution
The direction of wave must be opposite and frequencies will be same then by superposition, standing wave formation takes place.
