The five characteristics of plane progressive waves are:
- Plane progressive waves are waves that propagate through a medium in a single direction, creating a disturbance that moves in a straight line. This type of wave is often referred to as a “plane wave” because it creates a flat, two-dimensional disturbance in the medium.
- Plane progressive waves have a well-defined frequency and wavelength. The frequency is the number of waves that pass a fixed point in a given amount of time, while the wavelength is the distance between two consecutive peaks or troughs of the wave.
- Plane progressive waves have a constant amplitude, which is the maximum height of the wave’s disturbance. The amplitude of a plane progressive wave is the same at every point along the wave’s path.
- Plane progressive waves can be transverse or longitudinal. Transverse waves are waves in which the disturbance is perpendicular to the direction of propagation, while longitudinal waves are waves in which the disturbance is parallel to the direction of propagation.
- Plane progressive waves can be described by mathematical equations that define the wave’s properties, such as its frequency, wavelength, and amplitude. These equations can be used to predict the behavior of the wave and to calculate its properties at any point in time or space.

The neutron-proton ratio of an isotope is a measure of the number of neutrons in the nucleus relative to the number of protons. This ratio plays a role in the stability of an isotope because the forces that hold the nucleus together are affected by the number of protons and neutrons. In general, isoRead more
The neutron-proton ratio of an isotope is a measure of the number of neutrons in the nucleus relative to the number of protons. This ratio plays a role in the stability of an isotope because the forces that hold the nucleus together are affected by the number of protons and neutrons.
In general, isotopes with a higher neutron-proton ratio are more stable than isotopes with a lower neutron-proton ratio. This is because the strong nuclear force, which holds the nucleus together, is more effective at binding neutrons and protons when there are more neutrons present. The more neutrons there are, the more stable the nucleus will be.
However, there are some exceptions to this general rule. For example, isotopes with an atomic number of 2 or 8 have particularly stable nuclei, regardless of their neutron-proton ratio. This is because the strong nuclear force is most effective when there are equal numbers of protons and neutrons in the nucleus.
Overall, the neutron-proton ratio is one factor that determines the stability of an isotope, but it is not the only factor. Other factors that can affect the stability of an isotope include the total number of protons and neutrons in the nucleus and the energy levels of the nucleons.

Radioactive decay is the process by which an unstable atomic nucleus emits particles or electromagnetic radiation to become more stable. There are several different modes of radioactive decay, including alpha decay, beta decay, and gamma decay.
- Alpha decay occurs when an atomic nucleus emits an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. This type of decay reduces the atomic number of the nucleus by two and the mass number by four.
- Beta decay occurs when an atomic nucleus emits an electron or a positron, which are particles with the same mass as an electron but with opposite charge. This type of decay changes the nucleus from one element to another and increases the atomic number by one.
- Gamma decay occurs when an atomic nucleus emits a high-energy photon, which is a type of electromagnetic radiation. This type of decay does not change the atomic number or the mass number of the nucleus, but it does release a large amount of energy.
