Answer: 25×10⁵m⁻¹. is wave number and 75×10¹³Hz is frequency.

Explanation:

WAVE NUMBER=RECIPROCAL OF WAVELENGTH=1/WAVELENGTH

==>WAVE NUMBER=25×10⁻⁵×10¹⁰=25×10⁵m⁻¹.

FREQUENCY=VELOCITY OF LIGHT/WAVELENGTH.

                     =3×10⁸/4000A°

                     =0.75×10⁸×10⁷=75×10¹³Hz.

HOPE IT HELPS YOU.........................

THANK YOU.
