David Sang Solutions for Chapter: Properties of Waves, Exercise 1: Questions

Describe the motion of molecules of water as a ripple moves across the surface of the water in a ripple tank.

The two graphs shown are very similar to each other. What is the important difference between them?

Draw a diagram to show what is meant by the amplitude of a wave.

How could you find the wavelength of the ripples show in the figure?

If $10$ waves occupy $15.0 \mathrm{cm}$, what is their wavelength? 

If $100$ sound waves reach your ear each second, what is their frequency?

If $100$ number of sound waves reach your ear in each second, what is their period?

Are sound waves transverse or longitudinal?
