Question

Distance between node and next antinode in a stationary wave is 10 cm. Calculate the wave
length of the wave.​

Answer 1

Explanation:

wave lenght= node to node (or) anti node to anti node

length of node to anti node= anti node to node.

so length of wave= node to anti node is 10cm and that is equal to anti node to another node which is also 10cm

so, total length= 10cm+ 10cm=20cm
