Electromagnetic radiation with wavelengths between 0.4 and 0.7 micrometers is called:

Ultraviolet light
Visible light
Infrared light
Microwaves

The correct answer is: B. Visible light.

Visible light is a type of electromagnetic radiation that is visible to the human eye. It has a wavelength of between 380 and 700 nanometers, which is shorter than the wavelength of ultraviolet light and longer than the wavelength of infrared light. Visible light is made up of a spectrum of colors, from red to violet. The different colors of visible light have different wavelengths, with red light having the longest wavelength and violet light having the shortest wavelength.

Ultraviolet light is a type of electromagnetic radiation that has a wavelength shorter than visible light. It has a wavelength of between 100 and 400 nanometers. Ultraviolet light is invisible to the human eye, but it can be harmful to human skin and eyes.

Infrared light is a type of electromagnetic radiation that has a wavelength longer than visible light. It has a wavelength of between 700 nanometers and 1 millimeter. Infrared light is invisible to the human eye, but it can be felt as heat.

Microwaves are a type of electromagnetic radiation that has a wavelength of between 1 millimeter and 1 meter. Microwaves are used in many different applications, such as cooking, radar, and telecommunications.
