Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which section of the spectrum is the ONLY one we can see?
A
X-rays
B
Visible Light
C
Gamma Rays
D
Ultraviolet Rays
Explanation: 

Detailed explanation-1: -What is the visible light spectrum? The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

Detailed explanation-2: -The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10-7 m, which is violet) to 700 nm (7 x 10-7 m, which is red).

Detailed explanation-3: -The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is red and the shortest is violet. Common wavelengths of what we perceive as particular colours from the visible portion of the spectrum are listed below.

Detailed explanation-4: -The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays-all of which are imperceptible to human eyes.
