Question

All electromagnetic radiation is visible to the human eye. Please select the best answer from the choices provided

Answer 1

The correct answer is

b. False

It's actually the opposite: only a very small part of the electromagnetic spectrum is visible to human eye.

The electromagnetic spectrum consists of a huge range of wavelengths, spanning from gamma rays (with very short wavelength, at the order of 1 pm) to radio waves (with very long wavelength, at the order of kilometers). The only portion of this spectrum visible to the human eye is the "visible light", which has wavelengths between 400 and 700 nanometers approximately.

Answer 2

The statement is False. All the electromagnetic radiations are not visible to the human eyes.

Explanation:

The waves are defined as the disturbance produced in the medium particles. The wave is basically the physical phenomena that occurs in a medium and it is characterized by the amplitude, wavelength and the frequency of oscillating particles.

The waves are basically characterized as the transverse and the longitudinal based on the direction of oscillation. The transverse waves are the one in which the direction of oscillation is perpendicular to the propagation whereas in longitudinal waves, the direction of oscillation is along the motion of the wave.

The electromagnetic waves are the transverse waves that are formed by the perpendicular magnetic and electric field present in the medium. The complete electromagnetic spectrum is not considered to be in the visible range for the human eye. Only a small part lying in the wavelength of $4000-7000\,\AA$.

Thus, The statement is False. All the electromagnetic radiations are not visible to the human eyes.
