Question

The distance between node and adjacent antinode is 30 cm. the wavelength is

Answer 1

Thanks for the question. Please find the answer below:

Keeping in view that; the distance between node and adjacent antinode is 30 cm. the wavelength is 60cm.

A node is a point on a standing wave where the amplitude is minimum while antinode is the point of maximum displacement.

Answer 2

Answer:

120cm

Explanation:

We know that the distance between a crest and a successive trough is half wavelength i.e.

λ/2

Hence the distance between two successive antinodes is

λ/2

Exactly at the centre in between two adjacent antinodes there are particles which appear to be stationary. They vibrate with minimum amplitude.

Hence the distance between a node and its adjacent antinode is

λ/4
