02--- impossible phenomenon of longitudinal wave

Problem description

The impossible phenomenon of longitudinal wave is ？
A. Reflection phenomenon
B. Refraction phenomenon
C. Diffraction phenomenon
D. Polarization phenomenon

answer

The above questions should be D Options .

analysis

For reflection , Refraction and diffraction , For all light waves . However, the polarization phenomenon characterizes the propagation of light , The relationship between the vibration direction and its propagation direction . For shear waves , The vibration direction is perpendicular to the propagation direction , in other words , Its vibration direction is in any direction perpendicular to its propagation direction . So it can be Line polarized light , Circularly polarized light as well as Elliptically polarized light . And for longitudinal waves , According to its definition , Its vibration direction is always consistent with the propagation direction . So we can say that its vibration direction is a fixed direction , Can't be changed , So there is no polarization .
