Question

*We can see the light of wavelength between ___________.*

1️⃣ 200nm to 300nm
2️⃣ 400nm to 800nm
3️⃣ 250nm to 500nm
4️⃣ 100nm to 500nm​

Answer 1

Answer:

380 to 700 nanometers

More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

Answer 2

Answer: We can see the light of wavelength between 400nm to 800 nm.

Explanation: The part of the electromagnetic wave that can be observed by human vision is known as the visible spectrum. The visible spectrum in the electromagnetic spectrum spans from the infrared to the ultraviolet regions. Between the infrared and ultraviolet wavelength ranges is where the visible light falls. From 400 nanometers (violet) to around 700 nanometers (red) and sometimes to 800 nanometers, the human eye can sense the light spectrum. Due to biological limits, other electromagnetic radiations are either too small or too vast to be seen by the human eye.

The visible light is split up into a spectrum of colours as it passes through a prism. The wavelength of the colour red is 700 nanometers, while the wavelength of the colour violet is 380 nanometers. The spectrum of rainbow colours is made up of these colours, which are arranged according to wavelength.

Hence, correct answer will be (2) 400 nm to 800 nm.
