Is the light we see just wave of a certain frequency in an electromagnetic field?

Light is a form of electromagnetic radiation that is visible to the human eye. It is made up of particles called photons, which travel in a straight line at a speed of approximately 186,282 miles per second. Light can travel through empty space, as well as through certain materials, such as air and water.
Light and electromagnetic fields are closely related because light is a type of electromagnetic wave. This means that light is made up of oscillating electric and magnetic fields that travel through space. These fields are perpendicular to each other and are responsible for the behavior of light.
The electromagnetic spectrum is the range of all possible wavelengths of electromagnetic radiation. This includes visible light, as well as other forms of electromagnetic radiation such as radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. Each type of radiation has a specific wavelength and energy level.
The color of an object is determined by the wavelengths of light that it reflects. When light hits an object, some of the wavelengths are absorbed while others are reflected. The wavelengths that are reflected determine the color that we see. For example, an object appears red because it reflects red light and absorbs all other colors.
Light and electromagnetic fields have many practical applications in our everyday lives. Some examples include telecommunications (using radio waves), cooking food (using microwaves), and medical imaging (using X-rays). Other applications include using infrared radiation for night vision technology and ultraviolet radiation for sterilization processes.
