Embibe Experts Solutions for Chapter: Stationary Waves, Exercise 1: Maharashtra Board-2019

In stationary wave, the distance between a node and its adjacent anti-node is____. 

Explain the formation of stationary waves by the analytical method. Show that nodes and antinodes are equally spaced in stationary waves.

A stretched sonometer wire is in unison with a tuning fork. When the length of the wire is increased by 5%, the number of beats heard per second is 10. Find the frequency of the tuning fork.

A standing wave is produced on a string fixed at one end and free at other. The length of string must be an _______.
 

Show that all harmonics are present in case of an air column vibrating in a pipe open at both ends.

A sonometer wire 1 metre along weighing $2\mathrm{g}$ is in resonance with a tuning fork of frequency $300 \mathrm{Hz}$ Find tension in the sonometer wire.

A wire length $1 \mathrm{m}$ and mass$2 \mathrm{g}$ is in unison with a tuning fork of frequency $300 \mathrm{Hz}$. Calculate the tension produced in the wire.

In Melde’s experiment, when tension in the string is $10 g$ wt then three loops are obtained. Determine the tension in the string required to obtain four loops, if all other conditions are constant.
