Chapter 5: Q12DQ (page 1104)

Does it make sense to talk about the polarization of a longitudinal wave, such as a sound wave? Why or why not?

Short Answer

Expert verified

No, it does not make sense because the sound waves cannot be polarized.

Step by step solution

01

Definition of Longitudinal and Transverse Waves

The waves in which displacement of particles is parallel to the wave propagation direction are referred to as Longitudinal waves.

The waves in which displacement of particles is perpendicular to the wave propagation direction are referred to as Transverse waves.

02

Determine if polarization is possible in longitudinal waves

One can only talk of the polarization of the transverse waves because then one can say if the oscillations of the fields or particles of the medium occur in a line perpendicular to the direction or propagation or in a diffuse manner. With longitudinal waves, all oscillations are along the line of propagation so one cannot make similar discrimination.

Hence, it does not make sense to talk about polarization of longitudinal wave or sound wave.

A spherical air bubble in water can function as a lens. Is it a converging or diverging lens? How is its focal length related to its radius?

It has been proposed that automobile windshields and headlights should have polarizing filters to reduce the glare of oncoming lights during night driving. Would this work? How should the polarizing axes be arranged? What advantages would this scheme have? What disadvantages?

A student claimed that, because of atmospheric refraction (see Discussion Question Q33.2), the sun can be seen after it has set and that the day is therefore longer than it would be if the earth had no atmosphere. First, what does she mean by saying that the sun can be seen after it has set? Second, comment on the validity of her conclusion.

You use a lens of diameter and light of wavelength and frequency to form an image of two closely spaced and distant objects. Which of the following will increase the resolving power? (a) Use a lens with a smaller diameter; (b) use light of higher frequency; (c) use light of longer wavelength. In each case justify your answer.

An interference pattern is produced by eight equally spaced narrow slits. The caption for Fig. 36.14 claims that minima occur for f =3π/4, π/4, 3π/2 and7π/4. Draw the phasor diagram for each of these four cases, and explain why each diagram proves that there is in fact a minimum. In each case, for which pairs of slits are there totally destructive interference?
