Question

The range of wavelength of the electromagnetic radiation visible to us is

• A. $3600A^{\circ }-7800A^{\circ }$
• B. $8000A^{\circ }-9000A^{\circ }$
• C. $400A^{\circ }-800A^{\circ }$
• D. $1000A^{\circ }-4000A^{\circ }$

Answer 1

The correct option is A $3600A^{\circ }-7800A^{\circ }$

We know that the range of wavelength of visible light is:
$3600A^{\circ }-7800A^{\circ }$
Hence option $\left(a\right)$ is the correct answer.
