When a wave is an incident on any surface, a part of the incident wave is reflected and a part is transmitted into the second medium. If the wave is incident obliquely on the boundary, the transmitted wave can also be termed as a reflected wave.

10 Questions

1. In a standing wave the amplitude of a particle is fixed, but varies from particle to particle. True or False?
2. A pipe open at both ends has a fundamental frequency of 2Hz. If the pipe is closed at one end and half filled with water, what will be the fundamental frequency?
3. What is the minimum distance between a node & an antinode in a standing wave?
4. The equation of a wave is: y = 2sin(4x-3t). What will be the equation of the reflected wave from a free surface?
5. Consider the case of normal modes of vibration for the air column with only one end closed. What is the length of the air column for the fundamental harmonic?
6. Standing waves can be produced when two identical waves, having a phase difference of π, are travelling in the same direction. True or False?
7. If a standing wave is vibrating in the fourth harmonic and the wavelength is λ, what is the length of the string.
8. In a standing wave the amplitude of a particle is fixed, but varies from particle to particle. True or False?
9. If a string wave encounters a completely fixed end, what happens to its phase?
10. Consider standing waves in an air column with one end closed. What is a pressure node?
