Answer:
In a transverse wave, the vibration of the particles (or the direction of the oscillation in the case of electromagnetic waves) is perpendicular to the direction of propagation. This means, if the wave moves in the x-direction, the oscillations may be in the y-direction, for example, the plane waves are transverse waves.
Longitudinal waves, as the name says, are the waves where the oscillation is parallel to the direction of movement. In the case of mechanical waves, this type is called "compressional waves", an example of this can be the pressure waves or the sound waves. For the electromagnetic waves this case is not really common, but Maxwell's equations do lead to the appearance of longitudinal waves under some circumstances, for example, in plasma waves or guided waves.
Answer:
Stable nuclei will not undergo in nuclear decay reactions. Stability of nucleus depends upon the force between nucleons.
If there is strong attraction force between the nucleons then the repulsion force between the protons will be neglected over this strong force and the nuclei is stable.
Also we can check the stability of nucleus by the ratio of neutrons and protons in the nucleus.
here the stability of nucleus is more it the ratio lie between 1 and 1.2 i.e.
so the neutron to proton ratio will decide the stability of nucleus.
So it the ratio lie for above range of neutrons and protons then it is least likely to go radioactive decay.
