Question

electromagnetic wave of wavelength 1500 nm line in which region of the spectum​

Answer 1

$\color{red}{ANSWER}$

Wavelength range of infrared region is 10³nm - 10⁶nm.

It means given wavelength 1500 nm = 1.5 × 10³nm lies infrared region

Because wavelength 1.5 × 10³nm lies between 10³nm to 10⁶nm.

Typical sources of infrared region is cool cloud of dust and gas : planet , satellite.

Here I attached pic of electromagnetic radiations. I hope it will help you .
