"We find that energy of an electromagnetic wave is quantized; meaning that it is emitted and absorbed in particle-like packages of definite energy, called photons or quanta"?

This statement is correct. In quantum mechanics, electromagnetic radiation is described as being composed of discrete packets of energy called photons. These photons have a specific energy determined by their frequency, and they behave both as particles and waves. This quantization of energy is a fundamental aspect of the wave-particle duality of light and is a key concept in understanding the behavior of electromagnetic radiation at the quantum level.

The statement "We find that energy of an electromagnetic wave is quantized; meaning that it is emitted and absorbed in particle-like packages of definite energy, called photons or quanta" accurately summarizes the concept of energy quantization in electromagnetic waves. It means that electromagnetic waves do not exist as a continuous spectrum of energy, but rather in discrete units or packets called photons, similar to how particles behave in classical physics. Photons have intrinsic properties such as energy, momentum, and wavelength, and their energy is directly proportional to the frequency of the electromagnetic wave. This principle is fundamental to quantum mechanics and has profound implications in various fields of physics, chemistry, and technology.
