Yes, light is an electromagnetic wave. This was first proposed by James Clerk Maxwell in the 19th century and has been experimentally proven through various experiments and observations.
Light exhibits the properties of both a wave and a particle. As an electromagnetic wave, it can travel through a vacuum at the speed of light and can be described by its wavelength, frequency, and amplitude.
Light is a type of electromagnetic wave, along with other types such as radio waves, microwaves, and X-rays. All of these waves are forms of energy that travel through space at the speed of light and are characterized by their frequency and wavelength.
No, the human eye is only sensitive to a small portion of the electromagnetic spectrum, known as visible light. Other types of electromagnetic waves, such as infrared and ultraviolet, are invisible to the human eye but can be detected with specialized equipment.
The electromagnetic spectrum is a range of all possible frequencies of electromagnetic radiation. Light falls within a small portion of this spectrum, specifically the visible light range. The electromagnetic spectrum also includes other types of waves, such as radio waves, microwaves, and X-rays.
