Question

In which region of electromagnetic spectrum does the radiation having frequency of 7.5×10^14 hz lie?

Answer 1

Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV) and has frequencies that falls between $4.3×10^{14}Hz$ and $7.7×10^{14}Hz$.

$\therefore$ $7.5×10^{14}$ belongs to the Visible light region of the EM spectrum.

But to be precise $7.5×10^{14}Hz$ is the frequency of Violet light, which can have frequencies varying from $7.5×10^{14}$ to $7.7×10^{14} Hz.$
