Covalent bonds in a molecule absorb radiation in the ir region and vibrate at characteristic frequencies.

a molecular vibration absorbs radiation of wavelength 188 μm. what frequency (in s−1) corresponds to that wavelength? enter your answer in scientific notation.

Explanation:

The relation between frequency and wavelength is shown below as:

c is the speed of light having value

Given, Wavelength = 188 μm

Also, 1 μm = nm

So,  

Wavelength = m

Thus, Frequency is:

the answer would be a

ok whats the question if not i cannot you i need question and need a thing to answer
