B M Sharma Solutions for Chapter: Travelling Waves, Exercise 2: CONCEPT APPLICATION EXERCISE

How can one create plane waves and spherical waves?

Is an oscillation a wave? Explain.

Which parts of the curve in the figure shown represent compression and rarefaction for a longitudinal wave?

How would you create a longitudinal wave in a stretched spring? Would it be possible to create a transverse wave in the spring?

Waves are generated on a water surface. Calculate the phase difference between two points $A$ and $B$, when, $A$ and $B$ lie on the same wavefront at a distance of $2\lambda$ between them, 

Waves are generated on a water surface. Calculate the phase difference between two points $A$ and $B$, when $A$ and $B$ lie on successive crests separated by $1 \mathrm{m}$

Waves are generated on a water surface. Calculate the phase difference between two points A and B, when 

A and B lie on successive troughs separated by $1.5 \mathrm{m}$

Transverse waves are not produced in liquids and gases. Why?
