I wrote this code snippet and I'm having a problem with formatting. Can you help me with something? How do I get the values in scientific notation inside the f'' style formatting brackets? The code is here:

import numpy

def wave_analysis(wavelength):
    wavelength_m = wavelength*10**-9
    freq = 3e8/wavelength_m
    ang_freq = 2*numpy.pi*freq
    wave_num = 2*numpy.pi/wavelength_m
    
    print(f'The wavelength given is: {wavelength_m:.3} m\n'+\
          f'The frequency is: {freq:.3} Hz\n'+\
          f'The angular frequency is: {ang_freq:.3} Hz\n'+\
          f'The wave number k is: {wave_num:.3} /m\n')
system
maine yah code snipet likhaa he or mujhe formating main samasya ho rahi he.kya meri kuch sahaayta kar sakate ho?main epa '' style praroopan bracket ke andar vaigyanik sanketan main maan kaise praapt karun?code yahan he:

aayaat karnaa

def wave_analysis (tarang dairdhya):
    tarang dairdhya_m = tarang dairdhya*10 **-9
    freq = 3e8/tarang dairdhya_m
    ang_freq = 2*numpy.pi*freq
    wave_num = 2*numpy.pi/tarang dairdhya_m
    
    print (F'the tarang dairdhya diya gaya he: {tarang dairdhya_m: .3} m \ n '+\ _
          f'the aavriti he: {freq: .3} hz \ n '+\ _
          f'the koniya aavriti he: {ang_freq: .3} hz \ n '+\ _
          f'the wave number K he: {wave_num: .3} /m \ n ')
