Wavelike properties refer to the characteristics of a phenomenon that can be described using the concepts of waves. These properties include interference, diffraction, and reflection. Waves are oscillating disturbances that transfer energy from one point to another without the transfer of matter.

Particulate properties refer to the characteristics of a phenomenon that can be described using the concepts of particles. In this context, particles are discrete, indivisible units of matter with mass and charge, which follow the laws of classical physics such as Newton's laws of motion.

Electromagnetic radiation, such as light, can be described as waves. These waves consist of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of the wave's motion. Electromagnetic waves can be characterized by their wavelength, frequency, and speed.

Electromagnetic radiation can also be viewed as particles called photons. Photons are quanta of energy with no mass or charge, but they carry momentum and can interact with other particles. In many situations, treating electromagnetic radiation as consisting of photons can provide a more accurate description of the phenomenon.

Some key experiments supporting the view of electromagnetic radiation as waves include Young's double-slit experiment and the phenomenon of diffraction. Young's double-slit experiment shows that light exhibits interference patterns, which can be explained by the concept of wave superposition. Diffraction occurs when light passes through an aperture or around an object, and the resulting pattern can also be explained through the concept of waves.

The particle view of electromagnetic radiation is supported by experiments such as the photoelectric effect and Compton scattering. The photoelectric effect demonstrates that light can cause electrons to be emitted from a material, and the properties of this effect can be accurately described considering light as consisting of discrete photons with specific energies. Compton scattering shows that when X-rays interact with electrons, both the X-rays and the electrons behave as particles, transferring energy and momentum according to the principles of classical physics. In conclusion, electromagnetic radiation can be understood in terms of both waves and particles, depending on the experimental context and the particular phenomenon being described. Each of these views is supported by various experimental verifications, highlighting the dual nature of electromagnetic radiation.
